feat(manacore/web): unified time model — timeBlocks for all time data

Introduces a central `timeBlocks` table that owns the time dimension
(start, end, recurrence, live status) for all modules. Calendar, times,
habits, and todo modules keep only domain-specific data with a
timeBlockId reference. The calendar becomes a universal time view
showing events, tasks, habits, and time entries from all modules.

Key changes:
- New `$lib/data/time-blocks/` module (types, service, queries, collections)
- Dexie schema v3 with timeBlocks table + migration from existing data
- Calendar events store creates TimeBlock + LocalEvent pairs
- Times timer uses TimeBlock.isLive instead of LocalTimeEntry.isRunning
- Habits logHabit creates point-event TimeBlocks (with optional duration)
- Todo scheduled tasks create TimeBlock via scheduledBlockId
- Calendar views filter by blockType, show items from all modules
- All calendar views use getItemColor() for cross-module color support

Also includes mukke → music module rename.
