Fix normal radio report submission

The radio button was connected only to the emergency hold handlers, so a
normal Send request never reached _submit. Connect pressed for non-emergency
calls while keeping hold-to-confirm exclusive to emergencies, and add tests
for click, short-hold rejection and full emergency hold. Headless 249/249,
Python 94/94.

 - **Mouse look (v0.7.3):** guard look is handled in `GuardController._input()` (before GUI), not `_unhandled_input`; focus/click-back recaptures the cursor and the HUD is made mouse-transparent recursively. Regression tests cover yaw/pitch and HUD filters.
+- **Radio submit fix (v0.8.1):** `RadioPanel.action_button` now connects `pressed` for normal reports; `button_down/up` remains exclusive to emergency hold-to-confirm. Regression test covers both modes.
 - **Campaign/v0.8.0:** `Campaign` owns Hollywood → Joke Shop → TV Studio progression. `campaign.json`, `shift_results.json`, `settings.json` and versioned `shift_state.json` persist separately; pause saves a checkpoint, review Continue advances, Settings resets with confirmation. Difficulty keys are `easy/normal/hard` (`ai_difficulty`); scripted QA bypasses tutorial unless `--tutorial` is passed. Help is searchable and generated from `InputBindings.REMAPPABLE`.
 - **Tutorial (0.8.0 work):** `docs/tutorial.md` is the eight-beat design; `src/game/tutorial.gd` is the pure state machine, `TutorialOverlay` is the non-blocking card, and `GameManager` wires it with a safe visitor, suppressed spawns, persisted completion/skip and Settings replay. Scripted test/capture runs bypass it unless `--tutorial` is passed; `smoke_tutorial.gd` covers completion/replay/skip.
 - **Documentation ownership (2026-11-01):** `docs/architecture.md` §12 defines the source-of-truth map and consolidation rules. Obsolete/historical plan documents are removed rather than kept; current work belongs in `TODO.md`. README/development-status/Blender AO/Forward+ stale claims were corrected. The v1.0.0 gap register and 0.8/0.9/0.9.5/1.0 roadmap live in `TODO.md`.
