Send 10-digit card ID as plain text (keyboard-style input)

Browse Source 
- Sends card ID as plain text with Content-Type: text/plain
- Uses 10-digit zero-padded format (e.g., "0983187584")
- Tries /api/input first, falls back to /api/play
- Updated default URL to 100.94.163.117:8547
- Version bump to 1.2.0

LEGO Dimensions + Moonlight Drive-In Integration
Integrates the LEGO Dimensions portal reader with the Moonlight Drive-In
video player system using NFC card IDs (decimal format).
video player system using NFC card IDs (10-digit decimal format).
When a LEGO Dimensions disc is placed on the portal, it triggers
video playback. When removed, playback stops.
When a LEGO Dimensions disc is placed on the portal, it sends the
10-digit card ID as plain text to the player (like keyboard input).
v1.1.0 Changes:
- Now uses nfc_card_id (decimal) for lookups and API calls
- Mapping file keys can be decimal strings: "983187584": "path/to/video.mp4"
- API sends card_id as decimal integer for compatibility
v1.2.0 Changes:
- Sends 10-digit card ID as plain text (like keyboard entry)
- No JSON, just the raw card ID string
- Updated default API URL
