feat: add CLI status command, rewrite setup wizard, and modernize table renderer

Three interconnected CLI improvements:

New status command (cmd/status.go):
- Fetches live claude.ai subscription data using the claudeai client
- Renders rate-limit windows (5-hour, 7-day all/Opus/Sonnet) with
  color-coded progress bars: green <50%, orange 50-80%, red >80%
- Shows overage spend limits and usage percentage
- Handles partial data gracefully (renders what's available)
- Clear onboarding guidance when no session key is configured

Setup wizard rewrite (cmd/setup.go):
- Replace raw bufio.Reader prompts with charmbracelet/huh multi-step form
- Three form groups: welcome screen, credentials (session key + admin key
  with password echo mode), and preferences (time range + theme select)
- Pre-populates from existing config, preserves existing keys on empty input
- Dracula theme for the form UI
- Graceful Ctrl+C handling via huh.ErrUserAborted

Table renderer modernization (internal/cli/render.go):
- Replace 120-line manual box-drawing table renderer with lipgloss/table
- Automatic column width calculation, rounded borders, right-aligned
  numeric columns (all except first)
- Filter out "---" separator sentinels (not supported by lipgloss/table)
- Remove unused style variables (valueStyle, costStyle, tokenStyle,
  warnStyle) and Table.Widths field

Config display update (cmd/config_cmd.go):
- Show claude.ai session key and org ID in config output

Dependencies (go.mod):
- Add charmbracelet/huh v0.8.0 for form-based TUI wizards
- Upgrade golang.org/x/text v0.3.8 -> v0.23.0
- Add transitive deps: catppuccin/go, harmonica, hashstructure, etc.
