Add local database mirror for ServerManager persistence

[bgoncal]

Summary

Introduce a GRDB-backed sanitized mirror for ServerManager so non-secret server metadata can be recovered if Keychain entries are lost (e.g. during developer-account migration). Key changes:

• Add ServerManagerPersistence.swift: defines ServerManagerKeychain and ServerManagerMirrorStore protocols and Keychain-backed implementations/adapters.
• Add ServerManagerMirrorStore.swift: GRDB-backed ServerManagerGRDBMirrorStore that persists sanitized ServerInfo records.
• Add ServerInfoMirrorTable.swift and register the new serverInfoMirror table in GRDB initialization and DatabaseTables.
• Extend ServerInfo with mirroredForPersistence and mirrorPlaceholderToken to ensure secrets (tokens, webhook URLs, client certs) are stripped before persistence.
• Update ServerManagerImpl to use a mirrorStore: persist sanitized mirrors alongside Keychain, merge mirror+Keychain when reading (prefer Keychain), sync mirror on setup, and keep mirror in sync on add/remove/removeAll.

This ensures the app can restore server shells without exposing secrets outside the Keychain, while keeping Keychain as the source of truth.

Pull request overview

Adds a GRDB-backed “mirror” persistence layer for ServerManager so non-secret server metadata can be recovered if Keychain entries are lost (e.g., during developer account migration), while keeping Keychain as the source of truth for secrets.

Changes:

• Introduces ServerManagerMirrorStore + GRDB implementation and a new serverInfoMirror table to persist sanitized ServerInfo.
• Updates ServerManagerImpl to keep Keychain + mirror in sync, and to fall back to the mirror when Keychain entries are missing.
• Extends ServerInfo with sanitization helpers and updates unit tests/DB schema tests to cover the new table and mirror behavior.
