feat: local server terminal access

[szwabodev]

• added status logs before connection is made in terminal
• added enter the terminal feature to Settings -> Server -> Server dropdown
• added some common terminal texts to translations (en/pl)
• added expandable local server config in terminal modal with settings for port and username, saved in local storage
• added rerender of terminal on local config save
• modified terminal WSS to allow local server connections, with automatic generation of SSH key and authorized_keys if they don't exist (uses auto_generated-dokploy-local key name to not collide with others)
• added constant terminal container height to avoid jumping when terminal loads for the first time
