Fix error_too_long translation and tighten MCP search spec assertions

Corrected error_too_long message from "fewer than 5" to "10 or fewer"
to match SEMANTIC_IDENTIFIER_MAX_LENGTH.

Replaced be_present with specific assertions on item count and
identifier in MCP search_{projects,programs,portfolios} specs to
ensure the correct resource is returned, not just any resource.
