Use server-side date filtering for device event history chart

Browse Source 
The device event history chart previously fetched all events and filtered
client-side. This wires the existing created_from API parameter to the
frontend so filtering happens in the backend.

Also fixes a bug where the Today filter returned no results: rusqlite was
storing datetimes with a space separator ("YYYY-MM-DD HH:MM:SS+00:00")
while SQL filters used RFC 3339 with a T separator, causing string
comparisons to fail for same-day events. All datetime storage across
device_events, devices, and notifications is now consistently RFC 3339.
A migration converts existing records.
