options UI: anchor all file terminology on the manual's 'game file' (English review)

Full-string audit of the settings UI (front options + F10 overlay):
- front top-row label 'Save file' -> 'Game file' (the instruction
  manual's term)
- per-file row tag '(profile)' -> '(game file)', both UIs
- F10 unavailable value 'Select file' -> 'Select game file'
- kept: 'File N' values, the '(File N)' section annotation and the
  '(no file)' unavailable state (short forms; the annotation's host
  word is the section title, which says the file number)
- 'Bond file' now appears only in identifiers/config keys
  (Bond.* rows, watchSettings* names, ini keys), never user-visible
Docs: D357 plan section 4 is now the terminology record (final string
table); D358 finding notes the (profile) -> (game file) supersession.
