Batch 2: super space, missing partitions, USB check

[ifoknr]

Summary

• Super space (SuperSpace in Core): super size (from super-partition-name), logical partitions split into current slot, other slot, COW and unslotted, aligned to 1 MiB with room kept for metadata. A card on the Device → Partitions tab shows it in fastbootd.
• Room check before flashing (fastbootd): a single logical partition flash (sparse images counted at their written size) and an OTA flash are checked to fit at the fullest point of the writes. When they don't, the app says by how much and what could make room (the other slot's partitions, COW / a pending update) and asks.
• Missing partitions (MissingPartitions in Core): logical partitions an OTA writes but the phone lacks are created with create-logical-partition NAME 0 after extraction and before flashing, with a note on fastbootd's default group. The manual Create window shows the same note.
• USB check (UsbDiagnosis in Core, UsbScan over WMI in the app, System.Management package): finds missing/broken drivers with install steps, Qualcomm EDL (9008), MediaTek BROM/preloader, Unisoc and Samsung download modes, and phones in Android (offers adb reboot bootloader).

Tests

• Core: SuperSpaceTests, UsbDiagnosisTests: 172 passing.
• CI screenshots:
  • the fake phone has no odm, so the OTA flash must create odm_a before the first flash;
  • a 12 GiB sparse image (40 bytes on disk) must be refused for lack of room;
  • the USB check reads a stand-in device list.
