Adds a new GET /sync-bank route that runs sync_to_sheets (2026) + infer_payments + flush_cache,
capturing all output and displaying it on a styled results page. Adds "Tools: [Sync Bank Data]"
nav link to all templates.

Store git tag, commit hash, and build date as OCI-standard labels and a
build_meta.json file inside the Docker image. The Flask app reads this at
startup and displays version info in all page footers. Adds /version JSON
endpoint for programmatic access. Falls back to dev@local outside Docker.
