Increase MAX_ID_LEN to support longer service identifiers

Allow service IDs up to 64 characters to support SHA-256 hashes,
UUIDs, and other long unique identifiers. This increases memory
usage by ~98 bytes per service instance, which is negligible for
typical deployments.

The IDENT column width in initctl output adapts dynamically based
on actual ID lengths in use, so short IDs remain unaffected.
