feat(practice): flag suspiciously short laps and remove any lap in one click

Practice laps under 85% of the driver's own median (a likely shortcut)
are flagged: counted, but never a best lap, record or training stat
until approved. Timing and Race Day get a one-click Approve/Remove
panel, overlays show a warning mark, and any lap can be removed or
restored from Timing and Judging with undo.

Also sends judge corrections straight to the server so its hot-results
protection can no longer hold back a correction made right after a
passing.
