Turn any tag into a quality gate

Until now, only GoSmarter's own Rule Pack tags could stop a review in its tracks — anything you tagged yourself was just a label. Useful for sorting, but nothing stopped a flagged item quietly sailing through Quality Review.

Not anymore. When you create or edit a tag, you can now set it to Block, Flag, or Audit:

• Block tags actually hold up Approve on Order Quality Review and Mill Cert Review — the reviewer has to tick "Override block" and give a reason before it goes through
• Flag and Audit tags show up for awareness without getting in anyone's way
• The severity shows as a coloured symbol wherever the tag appears — on stock, certificates, orders, and in Manage Tags

Every override gets logged, so there's always a record of who let what through and why. Because "I'm sure it's fine" isn't a compliance process.

PS This is scoped to Order Quality Review and Mill Cert Review only i.e. a Block tag on an inventory item or order doesn't stop anything elsewhere in the app yet (e.g. it won't block reserving stock or creating an order).
