feat: RTL_433 protocol database import - iteration 1/5

- Expanded protocol database from 18 → 299 signatures (16.6x increase) - Imported 281 protocols from RTL_433 open-source database (286 total devices) - Created automated import script: scripts/import_rtl433_protocols.py - Generated rtl433_protocols_imported.py with timing/frequency/modulation data - Updated protocol_database.py to include RTL433_PROTOCOLS - All 26 tests passing Breakdown by category: - Weather: 116 protocols - Sensors: 36 protocols - TPMS: 25 protocols - Security: 23 protocols - Home Automation: 18 protocols - Other: 50+ protocols Frequency coverage: - 433.92 MHz: 248 protocols - 315.00 MHz: 32 protocols - 915.00 MHz: 1 protocol This provides comprehensive coverage of Sub-GHz IoT devices for accurate identification from raw RF captures.
