[PM-37255] feat: Wire fill-assist manager into vault sync and app startup

[aj-rosado]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-37255

📔 Objective

Connects the fill-assist manager to the rest of the app so rules are fetched and kept fresh automatically.

Changes:

• VaultSyncManagerImpl — calls fillAssistManager.syncIfNecessary() after vault data is stored; fill-assist failures are silently dropped and never affect vault sync
• VaultManagerModule — injects FillAssistManager into VaultSyncManager
• BitwardenApplication — injects FillAssistManager to trigger eager initialization; the init {} block subscribes to serverConfigStateFlow for config-change-triggered syncs

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR wires the existing FillAssistManager into app startup and the vault sync pipeline so fill-assist rules stay fresh. The integration is small and surgical: eager injection in BitwardenApplication, a non-suspending fire-and-forget call in VaultSyncManagerImpl after replaceVaultData, and the matching DI/test wiring. Failure isolation is correctly preserved — syncIfNecessary() returns immediately, launches work on the manager's own ioScope, and wraps the body in runCatching, so a fill-assist failure cannot affect vault sync.
