fix: Resolve majority of dialyzer type errors

- Fix leader election guard test for :undefined pid
- Fix cpu_sup.util() pattern matching to handle numeric return
- Fix encoding_utils to always return explicit nil when needed
- Remove unused finite_float? function
- Fix signal handler to match :ok return from :os.set_signal/2
- Remove redundant catch-all pattern in database metrics
- Fix Gridsquare pattern matching in info_live template
- Remove unnecessary nil check for calculate_course result
- Fix get_packet_received_at to not check for nil (always returns DateTime)
- Remove redundant catch-all pattern in weather format_weather_value
- Fix query builder to use from(p in Packet) instead of bare Packet atom

Reduced dialyzer errors from 49 to 6. Remaining warnings are mostly
false positives from template compilation and overloaded function specs.
