Introduces a ProblemManager that detects and surfaces actionable issues
(stale config, legacy frigate-hass-card resources, slow/failed streams)
via status bar indicators and notification popups with fix actions.
Whilst the Frigate support in this card is the best among camera
engines, the name incorrectly suggests that Frigate is a requirement.
Instead, to broaden the appeal, change to more camera agnostic name.
This does not suggest any change in priority, role or support for
Frigate.
This change is likely to be bug prone, due to the size of the rename --
the code contains 1500+ references to "Frigate" most of which make sense
to rename, some which do not, all of which needed human assessment.
- Closes#1298
BREAKING CHANGE: References to `frigate-card` in all kinds of
configuration need to be updated to `advanced-camera-card`. An automated
config upgrade should take care of the majority of usecases (click `Edit
-> Upgrade -> Save`), though may not be perfect.
