Consolidate rights-granting through a single function

grantRights() is now the only place a player's RightsForPlayer{N}
setting ever gets written. All three previous call sites (verify+cat
after chat tracking, cd+decode after /verify, and the all-players
grant from decoding) now delegate to it instead of duplicating the
same read-modify-persist logic.

The main point: since every grant now flows through one place, it can
notify the specific player over Mercure the moment they receive new
rights, instead of them only finding out by trying a command that
used to be "Unknown command".

Also includes an already-present (uncommitted) tweak allowing bare
chat/verify/decode console input without the leading slash - unrelated
to this change but sitting in the same file, so it's coming along.
