Adds support for Airbot Theia OSD

[freasy]

Adds support for the new Airbot Theia OSD chip.

• Prevents incorrect display of "no OSD chip detected" message when using Theia OSD.
• Disables features requiring Max7456 font device when using Theia OSD.

Airbot will release a new OSD chip "Theia" - it is a replacement for the MAX IC.

Requires:
#14391

Summary by CodeRabbit

• New Features

  • OSD now recognizes Airbot Theia OSD devices when the firmware API is v1.47 or newer.

• Bug Fixes

  • OSD UI visibility and enabled/disabled states refined to account for Airbot Theia presence and API version, improving accuracy of device detection and configuration indicators.

Walkthrough

A boolean state property haveAirbotTheiaOsdDevice was added to OSD decoding, computed from flags and API version >= 1.47. osd.initialize UI logic was updated to incorporate this property when deciding visibility/disabled state of Max7456-related UI elements.

Changes

Cohort / File(s)	Change Summary
OSD tab changes src/js/tabs/osd.js	Added haveAirbotTheiaOsdDevice to OSD.data.state (computed as bit_check(d.flags, 7) && semver.gte(FC.CONFIG.apiVersion, API_VERSION_1_47)). Updated updateOsdView logic: .noOsdChipDetect now checks haveAirbotTheiaOsdDevice === false; .requires-max7456-font-device-detected disabled condition updated to `!isMax7456FontDeviceDetected

Lack any hardware to test, but this shouldn't break existing functionality either. Approving to be ready for FW merge
