fix(module): use accessor = links syntax for spacetimedb #[table] macro

The spacetimedb v2 #[table] attribute uses `accessor = name` not `name = name`.
The `accessor` parameter specifies both:
- the SQL table name (used in subscriptions: SELECT * FROM links)
- the Rust method name (used in reducers: ctx.db.links())

Also fix delete/find calls to pass references (&id) not values (id)
as required by the SpacetimeDB API for primary key lookup methods.
