feat: Add vim mode to query editor and settings

[akozlev]

• Added @replit/codemirror-vim dependency for vim keybindings
• Add select field for user key-map selection in Behavior tab of the Setting modal,
• Added vim mode in Query Pane and Function editor if user has enabled it the settings
• Added custom styling to vim status panel to match aesthetics

Q: Is a good idea to add this to any other multi-line editor in the app? - suggestion from #106
