DRY pass #2, batch 8, F20: drawer titles and tag colour names come from strings.xml (#5372)

Destination carried its English title as a field, and NoteTint its colour
name; every other word on screen is a string resource. Destination.title()
now reads nav_notes/reminders/archive/trash (a tag's destination keeps its
name), and NoteTint.label is a @StringRes. Error fallbacks raised in view
models and the install receiver stay as constants: they are made outside
composition, with no Context to read a resource from.
