feat: product drafts, moderator edits, info history, unlisted products, tags and categories (#8)

Phase 2 of the plan in `docs/design.md` ("Next"): product info.

**Drafts**
- A new upload is a draft. Only its creator and moderators can see it, and nobody can get or wear it.
- After uploading, the website goes straight to the product's review page, where the creator checks its info and presses Publish.
- Drafts not published within 30 days are deleted (checked every 10 minutes), and their catalogs get `delete` entries in their changes feed.
- The console's overview shows a "Drafts" to-do.

**Editing is a permission check now** (`product:edit`, from #7)
- Moderators can edit anyone's product. They must give a reason, which the creator sees.
- Moderators can lock fields (`product:lock`). Once a field is locked, only people with `product:edit-locked` can change it, so the creator sees it greyed out with "Locked by a moderator."
- Raising a rating to adult is immediate for anyone who can edit. Lowering it takes `product:rate-lower` (moderators), and is refused while any revision's files are rated adult. With cases (phase 3), a creator's request to lower it will open a rating review.

**Info history**
- Every edit, publish, lock change and undo is recorded with who, when, what changed (before and after) and why.
- It's shown on the edit page to the creator and moderators.
- "Undo" puts back what an entry changed, as a new entry, by the same rules (a creator can't undo a moderator's change to a field that's now locked).
- Moderator actions are also in the creator's audit log.

**Unlisted products and tags**
- An unlisted product is left out of search, lists and creator pages, except for its creator. Its link still works and people can still get it.
- Tags: up to 10 per product, lowercased.
- `/products` filters by `tag` and `catalog`, and a product's tags link to the filtered list.
- People who don't manage a product don't see its state labels (draft, unlisted, locks).

**Console → Products**
- Lists your products with drafts included; moderators can switch to everyone's.
- Filters: draft, published, unlisted, locked, deleted, removed, plus search.
- Shows how many libraries each product is in, and an Edit or Review button.

**Category**
- A product can be filed under a different IMVU category from its parent's.
- The choices are every category path the hub has seen on any product's parent, plus each level of those paths. They're limited to the same top-level category as the parent's, so a product stays the same kind (clothing, furniture or rooms), which the proxy relies on for the shop and inventory tabs.
- The list grows as products are uploaded. IMVU's own category tree, if it has a public one, would replace it.
- Category works like the other info fields: it can be locked, it's in the history, and it can be undone. The product list's category filter, and everything that shows a product's categories (including what the proxy gets), use the chosen path.

**Migration** `0011_product_info`: new product columns and the `product_info_change` table. Existing products count as published (with `published_at` set from their creation date) and listed.

**Compatibility**
- `t5de-catalog` needs no change: the hub's new `draft` field in the registration answer is ignored, and the website doesn't rely on it.
- The proxy only loads products from libraries, and drafts can't be added to one.

**Checks**
- 44 API tests pass, including a new one for moderator edits, locks, history, undo, unlisted, tags, the console list and draft purging, and new checks for category choices.
- Type checks pass.
- On a local hub I loaded the pages as the creator, an admin, another person and a signed-out visitor.
- I submitted the forms through the website, the way a browser does without JavaScript: save info, publish, choosing a category (and undoing it), a moderator's save with and without a reason, save locks, and undo, including a creator's undo refused by a lock. Each saved or refused correctly with the right message.
- Not tried: the upload form's redirect after a real upload to a running catalog.
