fix(ui): unique icons for every node, fix sidebar icon rendering

- Add unique icon to every function: mail, send, code, terminal
- Add unique icon to every inline node: plus, x, minus, hash, type,
  toggle, filter, git-merge, braces, scissors, quote, shield, repeat
- Fix sidebar: use def.icon for all nodes (not just non-functions)
- Color icons by type: amber for inline, cyan for HTTP, zinc for built-in
- Add missing MOCK_FUNCTIONS: const/number, const/string, const/boolean,
  json/object (now 17 total: 4 HTTP + 13 inline)
- Regenerate seed SQL with updated icons
