fix: address PR #2770 review feedback for verbose/compact mode toggle

- Fix default value: compact mode (verboseMode=false) is now the default,
  matching PR description and intended UX
- Extract shared ToolStatusIndicator component to eliminate duplicate
  status icon rendering between ToolMessage and CompactToolGroupDisplay
- Memoize VerboseModeProvider context value to prevent unnecessary
  re-renders of all consumer components
- Clear frozenSnapshot on WaitingForConfirmation state to ensure tool
  confirmation UI remains interactive during mid-stream toggle
- Replace magic string 'Shell' with SHELL_NAME constant in ToolMessage
- Remove unused i18n translation keys (verbose/compact mode messages)
- Update snapshots for Footer and ToolGroupMessage tests
