feat: v1.0.0 stability enhancements and docker discovery UI

[Yashh56]

Description

This PR addresses several critical stability issues and enhances the frontend UI in preparation for the v1.0.0 release.

It introduces a read-only mode for the Add Connection dialog to prevent accidental modification of discovered Docker database credentials, refactors components for better code cohesion, fixes a flaky cache TTL test, and improves the reliability of the DB connectors.

Changes Included

• feat(ui): Added read-only mode for discovered databases in the AddConnectionDialog to protect auto-extracted container credentials.
• refactor(ui): Renamed DatabaseDetail to DatabasePreview to prevent routing conflicts and reorganized global hooks into feature-specific directories (src/features/home/hooks).
• fix(bridge): Resolved the flaky dbStore.test.ts by increasing the test TTL buffer and improved RPC error handling across services.
• feat(bridge): Implemented an LRU cache utility to boost connector performance and improved SQLite/Postgres connection stability.

Testing Checklist

• Bridge test suite passes 100% (dbStore flaky test resolved)
• Tested discovery of Docker containers and verified credentials map properly
• Verified frontend build passes with reorganized imports
