Finish the file API traversal fix by rooting both GET and SET operations at the
actual file-type directory instead of the process working directory. This blocks
`..` escapes from `config/` and `config/middlewares/` while preserving valid
in-root reads and writes.
Also harden the optional unauthenticated local API listener so it only starts on
loopback addresses (`localhost`, `127.0.0.1`, `::1`). This preserves same-host
automation while preventing accidental exposure on wildcard, LAN, bridge, or
public interfaces.
Add regression tests for blocked traversal on GET and SET, valid in-root writes,
and loopback-only local API address validation. Fix an unrelated config test
cleanup panic so the touched package verification can run cleanly.
Constraint: `GODOXY_LOCAL_API_ADDR` is documented for local automation and must remain usable without adding a new auth flow
Constraint: File API behavior must keep valid config/provider/middleware edits working while blocking path escapes
Rejected: Mirror the previous GET `OpenInRoot(".", ...)` approach in SET | still allows escapes from `config/` to sibling paths under the working directory
Rejected: Keep unauthenticated non-loopback local API binds and document the risk | preserves a high-severity pre-auth network exposure
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Treat `LOCAL_API_ADDR` as same-host only; if non-loopback unauthenticated access is ever needed, gate it behind a separately named explicit insecure opt-in
Tested: `go test -count=1 -ldflags='-checklinkname=0' ./internal/api/v1/file -run 'Test(Get|Set)_PathTraversalBlocked' -v`
Tested: `go test -count=1 -ldflags='-checklinkname=0' ./internal/config -run '^TestValidateLocalAPIAddr$|^TestRouteValidateInboundMTLSProfile$' -v`
Tested: `go test -count=1 -ldflags='-checklinkname=0' ./internal/api/... ./internal/config/...`
Not-tested: End-to-end runtime verification of fsnotify reload behavior after a valid in-root provider edit
