Brings stage 1 into stage 2: the gallery drag fix and the change that
follows Anomalous_TTS interface 13 (no server path picker, no storage
change or move, folders shown with the node's settings file).
Conflicts: the picker CSS, the storage-change activity label and its
locale keys are dropped; stage 2's model download and backup entries stay.
tests/tts_setup_api.mjs now checks the pretrained download route instead
of the removed storage and library routes, and that no export sends a
path on the computer.
