frontoptions: fix level-1 overlap (save-file row painted under the first content row) + off-by-one item mapping; (save) tag -> (profile); D357 values plan

- The front options screen numbers items 0..s_rowN (0 = the top
  save-file row, k = content row k-1), but the level-1 draw loop painted
  content row k at rowY(k) -- the save row's own line -- and mapped
  s_hl (item-numbered) straight into s_rowIdx (content-numbered): the
  'Save file' row overlapped the first content row, highlights/adjusts
  hit the wrong row, the last content row was dead, and s_rowIdx[s_hl]
  could read one past the built rows. Content rows now draw at rowY(k+1)
  and all s_hl -> s_rowIdx uses take s_hl - 1 (A-press, L/R repeat,
  reset-maintain); hit-test/cursor were already item-numbered and are
  untouched.
- Per-file row tag '(save)' -> '(profile)' (maintainer request), both
  UIs (front options + F10 overlay) plus the stale comments.
- docs/dev/D357-SETTINGS-VALUES-PLAN.md (PROPOSAL): row-by-row audit of
  current defaults/ranges/steps/displays vs the PD port (local checkout)
  and the Turok PC list (maintainer notes); proposals: mouse sensitivity
  as a x multiplier, deadzone as a whole-% key (D333 legacy-alias
  pattern), texture filter '3-Point' -> Bilinear, audio step 128 -> 328
  (whole-%), MSAA +16x, FPS-cap preset grid, FOV degrees; kResetDefaults
  lockstep gate + GE_WSPROBE_RESET re-verification.

Build clean (248 targets), headless menu boot smoke clean; visual
check of the front options screen + F10 owed to the maintainer.
