* fix(backends): make backend install ops idempotent unless forced

POST /backends/apply hardcoded force=true through
LocalBackendManager.InstallBackend, so applying an already-installed
backend re-downloaded and re-extracted the whole artifact every time.
API clients that ensure a backend exists at startup paid a full OCI
image pull on every boot.

Backend install ops now default to non-forced — an installed, runnable
backend short-circuits (the orphaned-meta reinstall path in
InstallBackendFromGallery is preserved) — and reinstall stays available:

- ManagementOp gains a Force field; the local manager passes it through
  instead of hardcoding true.
- /backends/apply accepts an optional "force" boolean in the body.
- The React UI install route keeps forcing, since its button doubles as
  the explicit "Reinstall backend" action.

Distributed installs already behaved this way (workers skip when the
binary exists unless force is set); this aligns single-node behavior.

* fix(backends): don't force-reinstall LOCALAI_EXTERNAL_BACKENDS on boot

The startup loop for LOCALAI_EXTERNAL_BACKENDS runs
InstallExternalBackend for each listed backend on every boot, and its
gallery-name path hardcoded force=true — so every start re-downloaded
and re-extracted each listed backend's OCI image even when it was
installed and runnable. Supervising apps that list several backends
paid several full OCI pulls per launch.

Give InstallExternalBackend an explicit force parameter (it only
affects the gallery-name fallback; URI installs always write) and pass:

- false from the boot loop and `local-ai backends install` (idempotent
  ensure — `backends upgrade` is the refresh path),
- op.Force from the local manager's external-URI op,
- the request's force on the worker install path and true on its
  upgrade path (behavior unchanged).
