Add machine-level watching for issue notifications

[Copilot]

Users can now watch specific machines to receive notifications for all new issues created on those machines, complementing existing per-issue and global watch capabilities.

Implementation

Schema

• Added machine_watchers junction table (machine_id, user_id) with cascade deletes and user_id index

Service & Actions

• toggleMachineWatcher() in src/services/machines.ts follows existing issue watcher pattern
• Server action toggleMachineWatcherAction() handles auth and revalidation

UI

• WatchMachineButton component on machine detail page matches existing issue watch button styling
• Displays watcher count with eye icon in sidebar

Notifications

• Modified createNotification() to query machine watchers for new_issue events
• Machine watchers receive both in-app and email notifications based on preferences

Example Usage

// Machine detail page now includes watchers in query
const machine = await db.query.machines.findFirst({
  where: eq(machines.initials, initials),
  with: {
    watchers: { columns: { userId: true } }
  }
});

const isWatching = machine.watchers.some(w => w.userId === user.id);

<WatchMachineButton 
  machineId={machine.id} 
  initialIsWatching={isWatching} 
/>

Machine watching operates independently from ownership notifications and global watch preferences. The notification system deduplicates recipients automatically.
