Add options/enum selector for parameters with enumerated values

[rubenCodeforges]

Description

Parameters that have enumerated/discrete values (e.g., SERVO_DSHOT_ESC with values 1-4, ARMING_CHECK, SERVO_DSHOT_RATE) currently display only the raw numeric value. Users cannot tell what each value represents without consulting external documentation.

Similar to how Bitmask parameters already have a dedicated "Bitmask" button and editor, parameters with enumerated options should have an "Options" dropdown or selector that shows the human-readable label for each value.

Examples

• SERVO_DSHOT_ESC: value 1 should show as DShot150, 2 as DShot300, etc.
• SERVO_DSHOT_RATE: value 4 - user cannot determine what rate this corresponds to
• ARMING_CHECK: value 1 shows as raw number, but description says "add values: 1=all, 2=barometer, 4=compass, etc."

Expected Behavior

• Parameters with enumerated values should display an options dropdown (similar to the existing Bitmask button)
• The dropdown should show the human-readable label for each valid value
• ArduPilot parameter metadata already includes Values fields that map numeric values to labels - these should be used to populate the selector

Actually ARMING_CHECK is a bitmask but it's not shown in ardudeck as so .. current bitmask behavior is so fine if enabled for it.
