Added 11 new interface languages: Italian, Hindi, Japanese, Polish, Brazilian Portuguese, Traditional Chinese, Indonesian, Vietnamese, Czech, Turkish and Korean (20 languages in total).
Reworded the support text and button in all languages. No change to how snoozing works.

1.1.0: You can now type the snooze time in plain words (e.g. "tomorrow 9:00", "holnap 9", "in 3 days"); the existing date/time fields still work. Two new options, both OFF by default: repeating rule for a sender, and bringing a snoozed message back earlier when someone replies. With both off, behaviour is unchanged.
1.0.27: Shorter toolbar label so it no longer crowds the compose window header.

Simpler right-click menu: the snooze times, Custom…, Settings and Support are now all directly under a single "Snooze – Remind Me Later" entry, instead of the previous double-nested submenu. No change to how snoozing works.

(v1.0.25 — internal review-compliance fixes: non-async message listener, removed an unneeded web_accessible_resources entry.)

Internal review-compliance fixes only; no change to features or behavior.
- Reworked the internal message listener to the recommended non-async pattern.
- Removed an unneeded web_accessible_resources entry (the pop-up dialogs are
loaded as extension pages and don't need it).
