docs(input): the V toggle, the harness switches, and the HUD line

Docs/controls.md documented the 0.1.0 bindings only, so the camera toggle added with
0.2.0 was undocumented for the player-facing set and the review switches were
undocumented everywhere. Adds the V row, a changes-since-0.1.0 note that first person
stays the default, and a table for -thirdperson / -walk / -qaselftest with the note
that the walking capture is driven per shot rather than by the switch.

The in-game HUD line gains 'V view' so the packaged build documents it too.

 - [x] Add third-person camera following the player body. Done 2026-11-09: `USpringArmComponent` + camera on the capsule, boom 340 cm, lag 8, and the body is the animated skeletal mesh with the skin material. Review shot 5 (`demo-third-person`, `Screenshots/README.md`) shows the rig; the shipped default view stays first person.
 - [x] Add first/third-person toggle. **V**, via `IA_ToggleCamera`; the toggle swaps the active camera and the body's visibility. `-thirdperson` on the command line starts in third person so the review is reproducible.
 - [x] Add camera collision to prevent clipping through geometry. The spring arm's collision test (`bDoCollisionTest`, probe 12 cm on `ECC_Camera`) shortens the boom instead of letting the camera pass through a wall. **Not yet exercised against a wall in a shot** — the spawn point has open space behind it, so this is implemented but unproven.

+- [x] Document any input changes. `Docs/controls.md` gains the **V** first/third-person toggle (first person stays the default), a "changes since 0.1.0" note, and a table of the review harness switches (`-thirdperson`, `-walk`, `-qaselftest`). The in-game HUD line now reads `WASD move · Mouse look · Space jump · V view · R reset · Esc pause`.
