feat: Remove Run Now, add source tracking, optimize dashboard

- Remove /run-now endpoint (use task priority instead)
- Add source tracking to worker_tasks (source, source_schedule_id, source_metadata)
- Parallelize dashboard API calls (Promise.all)
- Add 1-5 min caching to /markets/dashboard and /national/summary
- Add performance indexes for dashboard queries

Migrations:
- 104: Task source tracking columns
- 105: Dashboard performance indexes

 ### Overview
-When creating many tasks at once (e.g., product refresh for all AZ stores), staggered scheduling prevents resource contention, proxy assignment lag, and API rate limiting.
+Tasks are created with `scheduled_for = NOW()` by default. Worker-level controls handle pacing - no task-level staggering needed.
 
 ### How It Works
 ```
-1. Task created with scheduled_for = NOW() + (index * stagger_seconds)
+1. Task created with scheduled_for = NOW()
 2. Worker claims task only when scheduled_for <= NOW()
 3. Worker runs preflight on EVERY task claim (proxy health check)
 4. If preflight passes, worker executes task

 7. Repeat - preflight runs on each new task claim
 ```
 
+### Worker-Level Throttling
+These controls pace task execution - no staggering at task creation time:
+
+| Control | Purpose |
+|---------|---------|
+| `MAX_CONCURRENT_TASKS` | Limits concurrent tasks per pod (default: 3) |
+| Working hours | Restricts when tasks run (configurable per schedule) |
+| Preflight checks | Ensures proxy health before each task |
+| Per-store locking | Only one active task per dispensary |
+
 ### Key Points
 - **Preflight is per-task, not per-startup**: Each task claim triggers a new preflight check
-- **Stagger prevents thundering herd**: 15 seconds between tasks is default
-- **Task assignment is the trigger**: Worker picks up task → runs preflight → executes if passed
+- **Worker controls pacing**: Tasks scheduled for NOW() but claimed based on worker capacity
+- **Optional staggering**: Pass `stagger_seconds > 0` if you need explicit delays
