SaaS Alerts API Rules

# saas-alerts — Spectral ruleset (strengthened)
# Plain Spectral. Existing hand-authored rules preserved; measured rules added
# from this provider's own OpenAPI conventions by strengthen_ruleset.py,
# then self-validated against the spec.
#
# Provenance:
#   - servers-https-only: 100% of servers already https (error)
#   - servers-expected-domain: 1/1 servers on saasalerts.com
#   - query-params-casing: camel @ 67% (n=21)
#   - operationid-casing: camel @ 100% (n=5)
#   - schema-names-casing: pascal @ 100% (n=10)
#   - schema-properties-casing: camel @ 61% (n=57)
#   - operation-security-required: 5/5 ops declare per-op security
#   - operation-documents-401: 100% adherence
#   - pagination params observed: ['page', 'pageSize']
#   - merge: kept 9 existing, added 8 measured, upgraded 0
#   - added: servers-https-only, servers-expected-domain, query-params-casing, schema-names-casing, schema-properties-casing, security-schemes-defined, operation-documents-401, no-empty-descriptions
