refactor(sqlite-demo): use castAs for branded-id boundary casts in M:N examples

The new main baseline (TML-2605) trips the no-bare-cast ratchet on the
string->branded-id casts in the M:N example helpers (+10). Replace the
bare `as PostId`/`as TagId` casts with castAs<T> to keep lint:casts at
delta 0. Behaviour unchanged (casts are erased at runtime).
