Replace all 7 stub methods in src/bin/api/db/d1.rs with full working
implementations using the Cloudflare D1 API from workers-rs 0.5.
Implements:
- run_migrations: executes four DDL statements via db.exec()
- list_quotes: dynamic WHERE clause with positional params, COUNT query,
paginated SELECT, per-quote tag fetch
- get_quote: prepared statement with first::<QuoteRow>()
- get_random_quote: ORDER BY RANDOM() LIMIT 1
- create_quote: INSERT + batch tag insert + read-back for timestamps
- update_quote: auth check, dynamic SET clause, optional tag replacement,
read-back of updated row
- delete_quote: auth check, DELETE, returns DeleteResult enum
Also adds helper structs (QuoteRow, AuthRow, TagRow, CountRow),
fetch_tags() helper method, and unsafe Send/Sync impls required for
Arc<dyn QuoteRepository + Send + Sync> on single-threaded wasm32.
