Name the fn each rest-003 row ports

Four where cells pointed at game.rs for fns that live in game/ime.rs, or
held prose or a line -> fn arrow, so map-check reported no fn for them.
They now name Game::ime_preedit, preedit::set_preedit, Game::sync_ime and
Title::drop_file. Verdicts and notes are unchanged. The file's remaining
line 76 (Minecraft.run -> game.rs::run) is outside this repair and stays.

map-check tools/port_map/rest-003.tsv: the four rows above are gone from
the output; line 76 still reports no fn.
