feat(rds): implement RDS database and snapshot explorer

[Z9RTM]

Summary

Implements full AWS RDS database instance management (create, delete, orderable classes, security groups) and manual snapshots in Cloud Explorer.

• Defined RDS SPI contracts and schemas for DB instances and manual snapshots (databaseSchema.ts, snapshotsSchema.ts)
• Implemented AwsDatabaseAdapter with AWS SDK v3 RDSClient handling instance lifecycle (CreateDBInstance, DeleteDBInstance, DescribeDBInstances) and manual snapshots (CreateDBSnapshot, DeleteDBSnapshot, DescribeDBSnapshots)
• Added dedicated RDS instance creation form (CreateRdsInstanceForm) and manual snapshots view/panel (DatabaseSnapshotsPanel)
• Removed legacy un-namespaced RDS routes (/api/rds/*) in favor of the unified Cloud Proxy SPI

Closes #105

Greptile Summary

Adds AWS RDS instance and manual snapshot exploration through the unified Cloud Proxy SPI.

• Implements RDS instance creation, deletion, listing, inspection, orderable-class discovery, and snapshot operations.
• Adds dedicated instance-creation and snapshot-management interfaces with capability-aware runtime states.
• Removes the legacy RDS API and frontend paths.
• Updates the amd64 release binary to Bun's baseline musl target for compatibility with older CPUs.

Confidence Score: 5/5

The PR appears safe to merge, with the previous RDS form findings resolved and no new actionable defects identified.

The engine-change handler clears the selected instance class, provider-reported classes are used without fabricated fallbacks, and the subsequent release-target change remains compatible with the Alpine amd64 packaging path.
