feat: add copy connection URL button to database connection info drawers

[Kadxy]

What this PR does / why we need it?

When users need to connect to a database via external tools (e.g., DBeaver, Navicat, Redis Insight), they currently have to manually assemble the connection URL from the address, port, and password shown in the connection info drawer. This PR adds a "Copy connection URL" button so users can copy the full connection URL in one click.

Summary of your change

• Added a "Copy connection URL" button to the MySQL, PostgreSQL, and Redis connection info drawers, for both container and remote connection sections
• URL formats: mysql://user:pass@host:port, postgresql://user:pass@host:port, redis://:pass@host:port
• Passwords are encoded with encodeURIComponent to handle special characters
• Added i18n support for all 10 languages

Please indicate you've done the following:

• Made sure tests are passing and test coverage is added if needed.
• Made sure commit message follow the rule of Conventional Commits specification.
• Considered the docs impact and opened a new docs issue or PR with docs changes if needed.
