Log system with rotation

[anarchyysm]

Problem

Goal: logs persist on the SD card and do not grow indefinitely.
Estimated effort: 1 day

Proposed Solution

• Create Service/storage_api/include/tos_log.h
• Create Service/storage_api/tos_log.c
• Implement log writing to TOS_PATH_LOGS "/system.log"
• Implement rotation: when reaching 2MB, rename to system.log.bak and create a new system.log
• Implement SD check before every write (storage_is_mounted())
• Integrate with log_level values defined in config/system.conf (info, debug, error)
• Test: generate logs in a loop — confirm rotation triggers at 2MB
