feat: add bulk import for posts 24f1ca13

- Adds bulk post import at /admin/import — upload a zip of
.md/.markdown files with optional YAML-style frontmatter  (title, slug,
status, published_date, tags, description,  meta_image, alias, lang).  -
Files without frontmatter use the filename as title; missing  slugs
auto-generate via the existing slugify. Existing slugs  are skipped, so
re-uploading is safe.  - Reuses parse_attributes, slugify, opt_str, and
db::create_post; adds a status field to ParsedAttributes. Bumps   the
global body limit to 51 MB to accommodate the 50 MB zip  cap.

	41	+	- Bulk import posts from a zip of markdown files at `/admin/import`

42	43		## Structure
43	44

92	93		```
93	94
94	95		The resulting binary at `./target/release/posts` is self-contained with all assets embedded. Copy it to your server with a configured `.env` file and run it directly.
	96	+
	97	+	## Importing posts
	98	+
	99	+	Visit `/admin/import` and upload a zip containing `.md` or `.markdown` files. Each file may start with YAML-style frontmatter:
	100	+
	101	+	```markdown
	102	+	---
	103	+	title: My Post
	104	+	slug: my-post
	105	+	status: published
	106	+	published_date: 2025-01-15 10:00:00
	107	+	tags: rust, sqlite
	108	+	description: A short summary
	109	+	lang: en
	110	+	---
	111	+
	112	+	Post body in markdown.
	113	+	```
	114	+
	115	+	Supported keys: `title`, `slug`, `status` (`draft` or `published`), `published_date`, `tags`, `description`, `meta_image`, `alias`, `lang`. Files without frontmatter are imported with the title derived from the filename and a slug auto-generated from that title. Posts whose slug already exists in the database are skipped, so re-uploading the same archive is safe.
	116	+
	117	+	The zip can be up to 50MB. Asset references inside posts (images, etc.) are left untouched — pre-host them or upload them separately at `/admin/files`.
