…n.condition

Previously only the render call was gated on passesCondition; the switch
still ran filterOptions resolves (DB queries on relationship/upload),
blocks validation, and full recursion into hidden subtrees. Add an
early-exit guard so a failing condition writes a minimal state entry and
returns, skipping access checks, validation, switch processing,
filterOptions, and child iteration. The client re-requests form state on
condition flips, so the minimal entry is sufficient.

Now that the tabs branch unconditionally writes state[path] with
passesCondition, the early-exit guard no longer needs to exclude tabs
and tab field types. Dropping the exclusion skips child iteration for
hidden tabs containers and tabs whose admin.condition fails. The tab
branch is also simplified — incoming passesCondition is guaranteed true
past the guard, so tab visibility depends solely on its own
admin.condition.

The previous fix mirrored the state[field.id] write inside the
short-circuit, which required developers to remember that tab fields
have a dual-keyed state contract (state[path] AND state[field.id]).

Move that responsibility back to where it belongs — the tab branch —
and exclude tab from the short-circuit. The tab branch now:

- Uses the incoming passesCondition resolved by iterateFields instead
  of re-evaluating field.admin.condition.
- Writes state[field.id] unconditionally.
- Returns early when the tab is hidden, skipping recursion into
  descendants (matches the short-circuit's intent without duplicating
  its body).

Net effect is the same perf win with one tab-specific concern living in
one place.

Reorganize the tab branch so the flow reads linearly:

1. Strip-unselected check (return if not selected).
2. Write state[field.id] (the visibility marker the Tabs component reads).
3. Return early if the tab is hidden — no recursion needed.
4. Resolve child permissions and select scope.
5. Recurse into children.

Previously the permissions/select setup ran before the hidden-tab early
return, which was wasted work and obscured the control flow.
