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
