)

## Summary

Closes [RFC #3076](#3076)
by adding a share-friendly file format for AetherSDR themes plus the
import / export / drag-and-drop UI that operators need to actually swap
themes around.

**Depends on #3160** — currently targets `auto/theme-pr4` so the diff
shows only Phase 6's delta. Will retarget to main once #3160 lands.

## ThemeManager additions

- `exportThemeToFile(themeName, filePath, *err)` — dumps the active
theme's live state (or another registered theme's on-disk JSON) to an
arbitrary file
- `importThemeFromFile(filePath, *err)` — validates schema, picks a
destination name from the JSON's `"name"` field (file stem fallback),
sanitises against path traversal, refuses to clobber built-ins, suffixes
`(2)` / `(3)`… on name collisions, copies into
`~/.config/AetherSDR/themes/`, makes it active. Returns the final name
on success.

## Theme Editor changes

- **"Theme actions" menu** gains an Export… / Import… pair below the
existing Rename / Delete actions
- **Drag-and-drop**: drop one or more `.aethertheme` (or `.json` theme)
files anywhere on the dialog window → each imports + activates in order
- Drop validation refuses non-local URLs and any file whose extension
isn't `aethertheme` / `json` — arbitrary files get the no-go cursor at
drag-enter
- Cosmetic: removed the manual `▾` glyph from "Theme actions" button
label (QPushButton with `setMenu()` auto-renders one; the two collided)

## File format (`.aethertheme`)

Plain JSON, identical shape to the user-dir `themes/*.json` files (same
`schemaVersion`, `name`, `author`, `version`, `description`, `tokens`).
Sharing happens via file exchange — Discord, Discussions, gist, email
attachment. No hosted marketplace.

## Format compatibility

- `schemaVersion = 1` is current; `> 1` loads with a log warning instead
of refusing — unknown tokens round-trip unchanged so a future v2 theme
survives a v1 build
- Missing tokens on import fall back to built-in defaults via the
existing `seedBuiltinDefaults()` path

## Test plan

- [x] Builds clean (`--target all`)
- [x] Save As "My Glassy Plasma" → Theme actions → Export to file… →
save as `.aethertheme`
- [x] Switch to Default Dark → Theme actions → Import from file… →
re-imports + activates
- [x] Drag the same file onto the dialog → re-imports as "My Glassy
Plasma (2)"
- [x] Drop a non-theme file → silently refused at drag-enter
- [x] Single Qt-rendered dropdown arrow on the Theme actions button (was
two)

…eq + temp widget classes

Bundle the canonical 7-segment / 14-segment LCD-replica fonts every ham
rig (FlexRadio Maestro, Yaesu, Icom) uses for frequency / mode readout,
plus the matching DSEGWeather icon font.  All 13 TTFs total ~295 KB raw;
the qrc embedding bakes them into the binary so themes resolve them by
family name without depending on the system having them installed.

### Bundled assets

- third_party/dseg/DSEG7-Modern/   (6 weights: Light/LightItalic/Regular/
                                    Italic/Bold/BoldItalic)
- third_party/dseg/DSEG14-Modern/  (same six weights)
- third_party/dseg/DSEGWeather/    (single weight icon font)
- third_party/dseg/DSEG-LICENSE.txt + README.md preserved verbatim for
  attribution (SIL OFL 1.1 — explicitly permits bundling + embedding;
  not viral on application code).

### Plumbing

- resources/resources.qrc — new /fonts/ prefix exposes all 13 TTFs
- src/main.cpp — QFontDatabase::addApplicationFont() loader at startup
- ThemeManager.cpp seedBuiltinDefaults() — five new font.family tokens:
    * segment7  = "DSEG7 Modern"   (raw family)
    * segment14 = "DSEG14 Modern"  (raw family)
    * weather   = "DSEGWeather"    (raw family)
    * freq      = "DSEG7 Modern"   (widget-class — see below)
    * temp      = "DSEG7 Modern"   (widget-class — see below)
- Both bundled themes (default-dark.json, default-light.json) get the
  same five entries under font.family so the Theme Editor's font-family
  picker (PR #3160) surfaces them automatically.

### Widget-class tokens (freq, temp)

`font.family.freq` is read by both VfoWidget's frequency label/edit
and RxApplet's frequency label/edit — one Theme Editor pick re-themes
both surfaces in lockstep via the existing applyStyleSheet reverse-map.

`font.family.temp` is registered for future temperature surfaces
(band-conditions / propagation readouts) so they can theme
independently from freq when those widgets land.  No widget paints
with it yet.

Defaults to DSEG7 Modern so a fresh install gets the segment look out
of the box.  Operators who want a proportional / fixed look can pick
any installed family via Theme Editor → click `font.family.freq` row →
QFontDialog (#3160 added that picker).

… theme rename/delete (aethersdr#3160)

## Summary

Closes [RFC aethersdr#3076](aethersdr#3076
Phase 5 — every editable token namespace now has a working picker in the
Theme Editor, and saved user themes can be renamed or deleted from the
dialog without touching the filesystem.

## ThemeManager additions

- `setString(token, value)` — font-family setter; mirrors `setColor` /
`setSizing`
- `factoryColor()` / `factorySizing()` / `factoryString()` /
`hasFactoryValue()` — extend the factory-snapshot lookup beyond
gradients
- `deleteTheme(name)` — switches active theme to Default Dark before
unlinking; refuses on built-ins
- `renameTheme(oldName, newName)` — rewrites the JSON file's `"name"`
field + filesystem rename in lockstep; refuses on built-ins and name
collisions
- `isBuiltInTheme(name)` — detected by whether the recorded path is
inside the Qt resource bundle (`:/themes/`)

## Editor changes

The token list now surfaces **every** editable namespace. Font-family
tokens show the family name, integer tokens show "N px", gradient +
scalar colour rows keep the existing swatch + descriptor.

Click-menu adapts to the token's namespace:

| Namespace | Menu options |
|---|---|
| `color.*` | Existing flat ↔ gradient chooser |
| `font.family.*` | "Edit font family…" (`QFontDialog`) |
| `font.size.*` / `sizing.*` | "Edit size…" (`QInputDialog::getInt`,
0–96) |

A **"Reset to default"** entry surfaces at the bottom of the menu
whenever the token has a factory baseline. The route picks the right
setter based on the token's namespace + the factory value's shape
(gradient vs scalar colour vs integer vs string).

New **"Theme actions ▾"** dropdown at the left of the button row:

- **Rename theme…** — refuses on built-ins with a friendly message
pointing to Save As…
- **Delete theme…** — confirms before unlinking; switches to Default
Dark first so consumers don't render against a half-loaded token map

## Inspector overlay fix

The cyan tracking outline was leaking on top of the row's type-chooser
QMenu and the Theme actions dropdown. `ThemeInspector::eventFilter` now
early-returns and hides its overlay whenever **either**
`QApplication::activeModalWidget()` OR
`QApplication::activePopupWidget()` is non-null — QMenus register as
popups, not modals, so both checks are required to cover the full
child-interaction surface. Same auto-resume on close.

## Test plan

- [x] Builds clean (`--target all`)
- [x] `font.family.ui` → "Edit font family…" → QFontDialog → pick → UI
re-fonts
- [x] `font.size.normal` → "Edit size…" → spinbox → labels grow
- [x] `sizing.panel.padding` → spinbox → applet panels get roomier
- [x] Right-edit anything → "Reset to default" → restores from
`:/themes/default-dark.json`
- [x] Theme actions ▾ → Delete theme… (on a user-saved theme) → switches
to Default Dark + removes JSON file
- [x] Save As "My Test" → Theme actions ▾ → Rename theme… → "My Renamed"
→ file renames + active state follows
- [x] Inspect on + click font row → menu shows; cyan overlay stays
hidden through the QMenu and the subsequent QFontDialog
