generate turso:// URLs for Turso databases (#1059)

Databases identified as Turso (via the UUID type byte, `id[5] == 0x10`)
now display `turso://` URLs instead of `libsql://` in `db list`, `db
show`, and the shell's connection banner. SQLite databases keep
`libsql://`.

The built-in shell also accepts `turso://` URLs: the scheme is rewritten
to `libsql` right after parsing, since `libsql-shell-go` only
understands `libsql`/`ws`/`wss`/`http`/`https`. The shell library is
quite legacy at this point and the CLI should be moving to the tursodb
binary anyway, so for now the rewrite is just hacked in on the CLI side
rather than teaching the library about `turso://`.

Instance URLs (`--instance-url`) still use `libsql://`, since instances
are a sqld-only concept.

Includes a new `TestGetDatabaseUrl` covering Turso, SQLite, and empty-ID
cases, and updates the list test to expect the new scheme.
