⚡ Bolt: Batch MCP OAuth Token resolution

[Donach]

💡 What: Refactored injectPerUserOAuthTokens in apps/agor-daemon/src/register-hooks.ts to pre-fetch both shared and per-user MCP OAuth tokens using a single batch database query via a new getTokensForServers method on UserMCPOAuthTokenRepository. The results are indexed in an in-memory Map with compound keys (${serverId}:${userId | 'shared'}) for instant lookup.
🎯 Why: Previously, listing MCP servers resulted in N+1 database queries due to individual await userTokenRepo.getToken(...) calls inside a Promise.all loop. This caused significant latency on endpoints fetching large sets of tools/servers.
📊 Impact: Reduces database latency and connections by eliminating N+1 DB roundtrips. N queries are replaced with exactly 1 query, improving endpoint performance linearly relative to the number of returned servers.
🔬 Measurement: Verify by monitoring database query logs or tracing endpoint latency when querying find on the mcp-servers or session-mcp-servers endpoints.
