fix(client): address PR #36 re-review — 7 items from Hoshe + Tyre

Warnings: facing indicator tests use Godot-normalized rotation range
(-PI, PI] instead of raw addition (SW/W/NW in test_rendering,
West in test_client_p3). Suggestions: cache font in world_radial
_draw(), fix docstring on deactivate_insert() trigger, document
tile-coordinate system on _eval_player_near (D-066), add public
reset_facing_state() to InputMapper (D-030 testability).
