Vito Sansevero 2c3d3a58c4 feat(system): resolve every library path in one place
utils/library_location.py decides where the library lives: the
PROMPT_MANAGER_DATA_DIR folder (validated: absolute, never inside a folder
ComfyUI or Prompt Manager serves), an explicit database.default_path as
before, a node-folder library that was not moved, else ComfyUI's
user/__promptmanager. The database, diagnostics, config.json, logs and the
LoRA image cache all ask it, so a new install never writes into the node
folder and an existing one keeps every path until the user moves it.
"Keep it here" is persisted as library.keep_in_node_folder.

"""Where the library lives (#249 S6b): the one resolver for every data path.
The library is ``prompts.db``, ``config.json`` (it can hold the CivitAI key),
the safety backups beside the database, the logs and the LoRA image cache.
Inside the node folder an uninstall, a reinstall or a folder-replacing update
deletes it, so new installs keep it in ComfyUI's system user folder
``user/__promptmanager`` (``folder_paths.get_system_user_directory``), which
ComfyUI's ``/userdata`` HTTP API refuses to serve.
Resolution order (``resolve_library``):
1. ``PROMPT_MANAGER_DATA_DIR``: an absolute folder outside every folder
ComfyUI or Prompt Manager serves. It is used when it holds a library or
when no node-folder library exists; an empty one never replaces a
node-folder library (that one stays in use, and Move library targets the
environment folder). An invalid value is ignored and reported.
2. An explicit ``database.default_path`` in config.json, honoured as before
(a relative path is relative to the node folder). ``PROMPT_MANAGER_CONFIG_PATH``
still names config.json itself.
3. The default data folder once a move finished there (its marker says
``moved``), even before the old file was renamed.
4. A node-folder ``prompts.db`` that was not moved: it stays in use until the
user moves it.
5. The default data folder (new installs). Outside ComfyUI (no
``folder_paths``) the node folder, as before.
Nothing here moves, copies or creates data: it only reads the file system.
After a live move the process uses ``switch_to``'s location until restart.
This module imports only the standard library, so the logger can use it.
