Mass Schedule Distribution & Tablet Remote Start Protocol

[Copilot]

Summary

Implements the two-part Replay System integration described in the problem statement.

---

Part 1 — Schedule Distribution

How it works:

1. Admin generates a Schedule QR from the admin panel and presses "Show Tablet QR Code"
2. Scout opens the Schedule screen, presses "Scan Schedule QR"
3. App scans the QR, parses { server_ip, port, comp_code, year }, stores all fields persistently
4. Constructs https://{ip}:{port}/schedule/{year}{comp_code}_matches.csv and downloads it automatically
5. Downloaded CSV is saved to internal storage and immediately applied as the active schedule

Error handling (non-obtrusive Toasts):

• 403 → "Schedule download disabled. Ask field crew to re-enable it."
• 404 → "Schedule file not found on server."
• Network error → "Cannot reach replay server. Verify WiFi connection."

HTTPS / self-signed cert: Uses a trust-all X509TrustManager (required for LAN self-signed certs per spec). The HostnameVerifier validates against the configured server IP to prevent connecting to unknown hosts.

Part 2 — Remote Start

How it works:

1. Scout opens Settings → Replay Remote Start, presses "Scan Remote Start QR"
2. App scans the QR, parses { auth_key, start_url, server_ip, port }, stores all fields persistently
3. Scout enables the "Enable Remote Start" toggle
4. All four values (IP, port, auth key, start URL) are also manually editable in Settings
5. On the Info tab, a red "▶ Start Recording" button appears
6. Pressing it: immediately navigates to the Auto tab, then fires POST {start_url} with { auth_key } asynchronously
7. Result shown as a brief Toast — fire-and-forget, scouting is never blocked

Swipe lock: When remote start is enabled, swiping from the Info tab to Auto is blocked — the scout must press the Start Recording button (which fires the remote start) to advance. Tab-bar clicks still allow free navigation.

Error handling (non-obtrusive Toasts):

• 200 → "✓ Recording started"
• 401 → "QR code expired — scan a new Remote Start QR"
• 409 → "Already recording"
• -1 (no config) → "Scan the Remote Start QR in Settings first"
• Network error → "Cannot reach replay server"
