Unify Tower repeater builds on SD-primary OTA storage

Keep the deployed SD target and layout, select qualified internal delta storage when no card is usable, and retain exact SD bootloader-update gates. Add storage, capability, transfer, recipe, and release-selection regression coverage.

Also preserve mandatory runtime packet logging in canonical XIAO images when verbose build debugging is disabled, fixing the four stopped release-matrix qualification failures.
