chore: upgrade to 1.7.0+v2.7.5

Confirms immich-server at the latest v2.7.5 + holds the DB pin immich v2.7.5 ships
(14-vectorchord0.4.3-pgvectors0.2.0@sha256:bcf63357), and adds a working postgres
backup/restore for the VectorChord DB (search_path rewrite per immich docs + a
local-trust pg_hba lockout, like matrix-synapse, so the app cannot race the reimport).

 Just uncomment and edit the respective .env-files.

-# Postgres backup/restore hook for immich's VectorChord/pgvecto.rs `database` service.
-# Two image-specific constraints:
-#   1. Never DROP DATABASE — the bundled pgvecto.rs worker PANICs and crashes the server.
-#      So `pg_dump --clean --if-exists` does a per-object replace in the live DB on restore.
-#   2. Restore rewrites the dump's empty search_path back to `public, pg_catalog` so VectorChord
