Log files were opened lazily from logsWrite(), which runs on the FreeRTOS timer daemon task (priority 2). Telemetry frame polling is dispatched to that same task via async_call_isr(). When the LOGS directory is large (thousands of files), f_open() with FA_OPEN_ALWAYS has to scan the whole FAT directory and blocks the timer task long enough to starve telemetry polling, producing a brief "Telemetry lost" / "Telemetry recovered" at log start. Move the file open/close into the new logsHandle(), called cyclically from perMain() on the menus/UI task (priority 1). logsWrite() now only appends a line to an already-open file and never blocks on f_open(). Because the timer/telemetry task is higher priority, it preempts the directory scan running on the UI task, so telemetry keeps flowing while the log file is being created.

After logsWrite() reported a read/write error it set error_displayed and then no-op'd on every timer tick, leaving the file open and the timer firing empty callbacks until the user toggled logging off and on. The open-error path in logsHandle() already retried automatically, so the two error paths were inconsistent. Handle a pending error in logsHandle() (UI task): stop the timer, close the file, and retry a fresh open through the existing open path. A successful (re)open clears error_displayed and resumes logging; while the error persists the timer stays stopped and the file closed, and the popup remains deduplicated.

The previous change retried the open on every perMain() cycle after any error. For a persistent hard error (bad card / corrupted FS) that means rescanning a potentially huge LOGS directory indefinitely, which is wasteful and cannot succeed. Only a full SD card is treated as recoverable: sdIsFull() is a cheap check (no directory scan) and the condition clears when the user frees space, so logging resumes automatically. Any other error now stops logging until the user re-enables it (which clears error_displayed). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Backport of #7523 to 2.12. Fixes #7513.
Telemetry briefly drops when SD-card logging starts if the
LOGS/directory is large. Log files were opened lazily fromlogsWrite(), which runs on the FreeRTOS timer daemon task — the same task that dispatches telemetry frame polling. A largeLOGS/makesf_open(FA_OPEN_ALWAYS)scan the whole FAT directory and blocks that task long enough to starve telemetry.The fix moves the open/close into
logsHandle(), called fromperMain()on the UI task;logsWrite()only appends to an already-open file. On 2.12 the affected files (logs.cpp,sdcard.h) are identical tomain, so this is a clean cherry-pick.See #7523 for the full description.
Tested: X7 firmware + simulator build.
