Switch to overlay-only patching; remove sitecustomize.py

Patches to b2.py and restic.py are applied directly in the overlayfs at
PREINIT boot time. The sitecustomize.py import hook was belt-and-suspenders
that succeeded or failed alongside the file patch every time, providing no
genuine fallback.

- Delete patch/sitecustomize.py entirely
- apply.sh: remove sitecustomize install step; flatten if/elif/else structure;
  restore self-contained URL-fix logic in the restic.py BLOCK; rename overlay
  tag 'sc' -> 'mw'
- recover.sh: unmount overlays to restore original files immediately, no
  reboot required; kill-switch file prevents re-application on next boot
- uninstall.sh: remove sitecustomize.py removal section; update overlay tag
- install.sh: update preflight to check patch/apply.sh, not sitecustomize.py
- README: remove sitecustomize references throughout; update recovery docs

this repository on a **persistent ZFS pool** (your data pool, not `/tmp` or a
system path) and registering a **PREINIT initshutdownscript** in the TrueNAS

`middlewared` starts, patching `b2.py` and `restic.py` directly in the overlay
and re-patching the UI bundle.
If `/usr` is a read-only filesystem, `apply.sh` handles this automatically by
mounting a writable [overlayfs](https://docs.kernel.org/filesystems/overlayfs.html)
on top of the relevant directories. The overlay lives in `/run` (tmpfs) and is
recreated on every boot. No extra configuration is needed.
## Python version compatibility
`sitecustomize.py` uses the `find_spec` / `exec_module` import hook API
(Python 3.4+; the older `load_module` form was removed in Python 3.12).
Compatible with all Python versions shipped by TrueNAS SCALE.

TrueCloud provider patch — sitecustomize.py
Installed into Python site-packages on every boot by apply.sh.
Hooks two middlewared module imports using the find_spec / exec_module API
(required for Python 3.12+, which ships with TrueNAS SCALE 25.x / Debian 13):
middlewared.rclone.remote.b2
Adds get_restic_config() so the native restic B2 backend works.
Restic repo URL: b2:<bucket>:<folder> (colon separator, restic 0.16.x)
Auth: B2_ACCOUNT_ID, B2_ACCOUNT_KEY
middlewared.plugins.cloud_backup.restic
Fixes the URL builder for providers with no hostname component, and
converts the slash separator to a colon for B2 (restic 0.16.x format):
Stock code: f"{rclone_type}:{url}/{remote_path}" → "b2:/bucket/path"
Patched: "b2:bucket:path" (leading slash stripped, / → : for B2)
Both patches are no-ops if the module already provides the functionality
(i.e. a future TrueNAS version adds native support). All errors are caught
and written to stderr so middlewared always starts regardless of patch state.
