Sun Catering v17.5.18

- Added workspace/account isolation for the browser working copy. Orders, clients, finance, stock, employees, suppliers, loyalty data, settings and other sun* company data no longer remain attached to the next signed-in account.
- Before leaving or switching a workspace, the current local working copy is saved to IndexedDB under that workspace. The target workspace is then restored from its own local snapshot or pulled cleanly from Supabase.
- Upgrade safety: an existing v17.5.x local database is automatically adopted by its already configured workspace; if the old configured workspace differs from the next login, the old data is captured separately instead of being attached to the new account.
- New companies start with the current official 113-position catalog while orders, clients and other working data start empty.
- Existing catalog boxes remain independently editable inside each company after the initial copy.
- Catalog JPEG files were recompressed/resized conservatively (max 1500 px side, JPEG quality 80) to reduce distribution size without changing file paths or format.
- Removed the obsolete prebuilt 9 MB static catalog PDF. The visible catalog PDF button already generates the current catalog on demand.
- PWA cache/version bumped to v17.5.18.
