fix(packets): correct dict iteration syntax in Telemetry.identify_packet

The method was attempting to iterate over target_packets using tuple unpacking, but `.items()`
was missing from the dict iteration. This would cause a TypeError since Python dictionaries
require `.items()` for key-value pair iteration.

Changed:
`for _, packet in target_packets:`
to:
`for _, packet in target_packets.items():`

This ensures proper dictionary key-value pair iteration when identifying packets in tlm_unique_id_mode.
