refactor: Extract event key Intent format to single source of truth

[williscool]

Added toIntentString() and fromIntentString() methods to EventAlertRecordKey class to ensure the event key format used in Intent extras is defined in one place. This prevents format mismatches between serialization and parsing.

• EventAlertRecordKey.toIntentString(): Serializes key for Intent extras
• EventAlertRecordKey.fromIntentString(): Parses key from Intent extras
• Updated ActiveEventsFragment to use toIntentString()
• Updated ApplicationController to use fromIntentString()

---

Note

Unifies the event key format used in Intent extras by making EventAlertRecordKey the single source of truth.

• Adds toIntentString() and fromIntentString() to EventAlertRecordKey for Intent serialization/parsing
• Replaces manual string building in ActiveEventsFragment with it.key.toIntentString() when launching SnoozeAllActivity
• Replaces ad-hoc parsing in ApplicationController.snoozeSelectedEvents with EventAlertRecordKey.fromIntentString()
