Fixes #30458 Contributor docs PR: https://github.com/fleetdm/fleet/pull/30651 # Checklist for submitter - We will add changes file later. - [x] Input data is properly validated, `SELECT *` is avoided, SQL injection is prevented (using placeholders for values in statements) - [x] If database migrations are included, checked table schema to confirm autoupdate - For database migrations: - [x] Checked schema for all modified table for columns that will auto-update timestamps during migration. - [x] Confirmed that updating the timestamps is acceptable, and will not cause unwanted side effects. - [x] Ensured the correct collation is explicitly set for character columns (`COLLATE utf8mb4_unicode_ci`). - [x] Added/updated automated tests - Did not do manual QA since the SCEP client I have doesn't support ECC. Will rely on next subtasks for manual QA. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Introduced Host Identity SCEP (Simple Certificate Enrollment Protocol) support, enabling secure host identity certificate enrollment and management. * Added new API endpoints for Host Identity SCEP, including certificate issuance and retrieval. * Implemented MySQL-backed storage and management for host identity SCEP certificates and serials. * Added new database tables for storing host identity SCEP certificates and serial numbers. * Provided utilities for encoding certificates and keys, and handling ECDSA public keys. * **Bug Fixes** * None. * **Tests** * Added comprehensive integration and unit tests for Host Identity SCEP functionality, including certificate issuance, validation, and error scenarios. * **Chores** * Updated test utilities to support unique test names and new SCEP storage options. * Extended mock datastore and interfaces for new host identity certificate methods. * **Documentation** * Added comments and documentation for new SCEP-related interfaces, methods, and database schema changes. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
