Gate courier handover on direct announces and isolate store test

Browse Source 
Envelopes are removed from the courier store optimistically, so releasing
them on a relayed (multi-hop) announce risks losing carried mail to a
speculative flood that never reaches the recipient. Handover now also
requires the announce to have arrived directly (full TTL), i.e. an actual
encounter with a live link; regression test builds a relayed copy of a
genuinely signed announce (TTL is excluded from announce signatures).

Also make CourierStore's on-disk location injectable so the persistence
test round-trips through a temp directory instead of wiping the real
Application Support store, and reattach BLEAnnounceHandler's doc comment
to the class it describes.
