Paul Nothaft 9050affd8d fix(security): unauth share_token leak (HIGH) + restore path-traversal, logo file-read, branding path keys (#946)
* fix(security): stop unauth share_token leak + block restore path-traversal, logo-path file read, branding path keys

* test: update resolveLogoFile for the c7x5 containment (reject outside-storage absolute paths, keep inside)

* fix(security): codex round-1 — escape LIKE wildcards in share-link resolve, keep in-storage absolute logos, guard restore verification

- shareLinkService: escape %/_ in the link_partial LIKE fallback so an
  anonymous /resolve/____… wildcard can't match an arbitrary share_link and
  leak its bearer token (reopened GHSA-rh8r). Explicit ESCAPE for SQLite.
- resolveLogoFile: re-add the raw absolute candidate but keep it subject to
  the storage-root containment filter (GHSA-c7x5) so legit in-storage
  absolute logos resolve while /etc/passwd stays rejected.
- restoreService: apply the same pathEscapes guard in post-restore
  verification so a skipped traversal entry isn't fs.access'd/hashed.
