…ment (#2779)

## Summary

Surfaces the data already collected by `FlexWaveformModel` (merged in
#2759) in a non-modal, geometry-persistent dialog at **File →
Waveforms**, mirroring SmartSDR's layout and location.

- **WFP status bar** at the top: power indicator (●), ready indicator
(●), and IP address — all live-updating via
`FlexWaveformModel::wfpStatusChanged`
- **Waveform list**: one row per installed waveform or Docker container,
with name, version, and type badge — live-updating via
`FlexWaveformModel::waveformsChanged`
- **Restart** button per row — fire-and-forget, no confirmation; sends
`waveform restart <name>`
- **Remove** (container) / **Uninstall** (legacy .wfp) button per row —
`QMessageBox::question` confirmation before sending `waveform
remove_container <name>` or `waveform uninstall <name>`
- Install omitted intentionally — Docker containers are managed at the
radio/firmware level, not from the client

## Implementation

`WaveformsDialog` inherits `PersistentDialog` (geometry-persist +
frameless-chrome handling) and takes a `FlexWaveformModel*` in its
constructor. No refresh logic in `MainWindow` — the dialog wires
`FlexWaveformModel` signals directly. `showOrRaisePersistent` handles
lazy-construct, raise-if-open, and frameless toggle registration
automatically.

## Test plan

- [x] **File → Waveforms** opens dialog; re-triggering raises it rather
than opening a second
- [x] WFP status shows correct power/ready state and IP address
- [x] `freedv-flex` (or other container) appears in the list with
version and `[Container]` badge
- [ ] **Restart** sends `waveform restart freedv-flex` — visible in
radio log
- [ ] **Remove** → cancel → no command sent; **Remove** → confirm →
sends `waveform remove_container freedv-flex`
- [ ] Disconnect from radio → list empties, status clears (driven by
`FlexWaveformModel::clear()`)
- [x] Frameless mode toggle applies correctly

… PR 8) (#2953)

Eight docs leave the top-level docs/ tree, partitioned by purpose:

docs/archive/ — historical planning/session notes, kept for grep
context:
  - issue-2136-feasibility-report.md     (PR #2759, shipped)
  - issue-2136-implementation-plan.md    (PR #2759, shipped)
  - TX_SYNC_FIX_REPORT.md                 (PR #353, RadioModel.cpp still
    references the report by name)
  - aether-dsp-session-notes.md          (#796 maintainer notebook)

docs/data/ — reference fixtures (not bundled, not runtime):
  - SSDR.settings + SmartSDR.exe.config   (SmartSDR parity reference)
  - rxapplet_mode_settings.csv            (per-mode RX control research)
  - vfo_mode_filters.csv                  (VFO filter-preset research;
    VfoWidget.cpp comment updated to new path)

Kept in docs/ (still active):
  - audio_test_plan.md  (17 KB, edited 2026-04-29, ongoing test plan)
  - profile-import-export-manual-checklist.md (PR #2641 QA checklist)

Both new dirs include a one-paragraph README explaining the convention
so a future maintainer doesn't have to guess what belongs where.

Cross-references audited:
  - AppSettings.h:9 mentions "SmartSDR's SSDR.settings" as a concept,
    not a path — no change.
  - RadioModel.cpp:3991 references TX_SYNC_FIX_REPORT by name — no
    change, file is findable via grep/find.
  - VfoWidget.cpp:3324 carried a literal "docs/vfo_mode_filters.csv"
    path — updated to docs/data/.

Verified with a clean local Release build (cmake --build … --target
AetherSDR exits 0).

After this PR, docs/ contains 18 markdown files (architecture/user
docs), the assets/ subdir from PR 5, and the new archive/ + data/
subdirs — matches the acceptance criteria in the cleanup plan.

Principle I.
