Vito Sansevero 57ab85b002 feat(thumbnails): keep previews in one folder, set from config.json (#320)
thumbnails.location in config.json can now name one folder for every
source's previews: <folder>/<source key>/<rel>_thumb<ext>. A source key is
a readable slug plus a short hash of the source's identity, stored in the
folder's marker (.promptmanager-thumbnails.json) with the install that
made it. Serving, on-demand and capture writes, listings, clear, delete,
duplicates, the temp sweep and History covers all follow it; a leftover in
<source>/thumbnails is never served and other text under thumbnails/ is
refused.

A missing, unplugged or foreign folder is unavailable (a probe checks it
every 5 s within 2 s; a stalled or failing store call flips it at once):
originals are served, nothing is written anywhere, the folder is never
re-created, and generate, convert and clear answer 409
location-unavailable. A bad config value is unavailable too, never a
fall-back to the sources.

No UI yet: POST /settings refuses thumbnail_location (409
location-needs-move); GET /settings reports it with its path, the
thumbnail status without one. Sources inside or around the folder and a
library move into it are refused.

"""Library location routes (#249 S6b): where the library lives, Move, Keep.
- ``GET /prompt_manager/system/library`` → ``{success, location}``: the
database's path (relative to ComfyUI, as the statistics show it), why it is
there (``source``: ``default``, ``environment``, ``config`` or
``node_folder``), whether it can move and where to (``target``), the
"Keep it here" choice (``keep``), whether to offer the move (``offer``:
movable and not kept), a ``problem`` code and the database's size. The
System Overview carries the same object as ``location``.
- ``POST /prompt_manager/system/library/move`` → 202 ``{job}``: the
``library_move`` job, ``exclusive`` (it runs alone and every other job,
legacy-page operations included, is refused while it runs), not
cancellable. It copies, verifies and switches the live library
(``database/library_move.py``) and ends with one truthful line; a failure
leaves the library in the node folder, unchanged. Refused before any job
starts: 400 ``not-movable``/``same-folder``/``target-invalid``, 409
``target-has-library``/``target-conflict``/``busy``, 507
``insufficient-space``.
- ``POST /prompt_manager/system/library/keep {keep: bool}`` persists
``library.keep_in_node_folder`` through the config store and answers the
new location.
Errors are ``{success:false, code, error}`` and never name a path.
