Rocky 23689925dd fix: light-mode accent + keyboard preview textbox
Two review-driven fixes, scoped narrowly to the two files the user
flagged. The broader uncommitted changes (Engine mode wiring,
SpeechAnalyzer, locale picker, etc.) belong to a prior agent pass and
are intentionally left out of this commit.

1. Light-mode accent is no longer the dark-mode green (#3AA05A).
   Both the system `AccentColor` asset and `Palette.light.accent`
   (plus `.accentMuted` / `.accentGlow`) now use Apple system blue
   (#007AFF). On a near-white surface the green read as "garden
   centre" and clashed with every iOS HIG-styled control. Dark
   palette's accent stays green — the keyboard extension is always
   dark, and green-on-dark is the more legible pairing for the
   polish/active affordance.

2. The keyboard preview's "textbox" is now a real `TextField` and
   the recognized text actually lands in it.

   Before: `mockTextField` was a static `HStack` (icon + "Type
   here…" placeholder). `cyclePhase()` had a comment
   "// Local engine skips processing — insert happens
   immediately." but the insert was never wired up — the user
   tapped the disc, the stub transcript appeared briefly in the
   transcript line, then vanished on the next tap with nothing
   landing in the top box.

   After:
   - `mockTextField` is a real `TextField(text: $typedText, axis: .vertical)`
     with a clear-X button, vertical growth (1-4 lines), and the
     accent-coloured cursor. The user can also type into it directly.
   - `cyclePhase()` calls `insertRecognizedText()` on the
     recording→idle (local) and processing→idle (cloud) transitions,
     so the (mock) recognized transcript appends to the textbox with
     a leading space when the existing text doesn't already end in
     whitespace — matches what `textDocumentProxy.insertText` does
     for the real keyboard.

   This only changes the in-app preview; the real keyboard extension
   already inserts via `textDocumentProxy` and is untouched.

Build: BUILD SUCCEEDED on iPhone 17 Pro / iOS 26 simulator.
Tests: 21/21 pass (no test changes — visual + App-Group code paths
already covered).
