Import missing French localization resources

[Copilot]

This adds the French translation set attached to the issue into Mission Planner’s existing localization layout. The change fills gaps in the current French coverage and refreshes several existing French resource files with the provided translations.

• French UI resource coverage

  • Adds missing fr resources for configuration views and setup flows that did not yet have French localization.
  • Includes new French resources for:
    • InitialSetup
    • HUDT
    • several configuration panels such as ConfigAC_Fence, ConfigADSB, ConfigESCCalibration, ConfigFriendlyParams, ConfigHWBT, ConfigHWParachute, and ConfigMotorTest

• French translation refresh

  • Updates existing French .resx files across:
    • GCSViews
    • GCSViews/ConfigurationView
  • Refreshes translations for major screens including FlightData, FlightPlanner, Help, and multiple vehicle/configuration pages.

• Scope

  • Resource-only change.
  • No application logic, runtime behavior, or project wiring was changed.
