The 14 phase-related profile columns (warmup/cooldown per workout type,
plus an unused Interval pair) added more granularity than wanted. Migration
0006 drops all 14 and adds a single warmup_minutes/cooldown_minutes pair
applied uniformly to every fixed-duration workout type; Interval still
detects phases from lap data directly and ignores this setting. Restores
a simplified Phase detection section in the Profile UI with just the two
fields.
Add Profile table to store Garmin credentials and engine configuration
parameters. Implements GetProfile() and UpdateProfile() store methods with
comprehensive test coverage. The profile singleton row is automatically
initialized on migration and persists all configuration state.
