M7 (v0.4.0, D387): ship AllUnlocked as loudly-documented EXPERIMENTAL/irreversible

Per the user's release decision, keep the toggle (default OFF) but make it
impossible to miss in-game: the row is now labelled 'All unlocked
(EXPERIMENTAL)' and its ON value renders 'ON - UNSAFE' in both the F10
overlay and the front PC Options screen (both read the shared row table).
ON value now bright-highlights like a normal On. Port-only, display-only
(config still stores 0/1); a safe architecture is v0.5.0 work.

Housekeeping: track docs/dev/M7-ALLUNLOCKED-PLAN.md (records the decision);
gitignore the stray repo-root Python/ install; refresh the D387 status.
