feat: visual redesign, setup wizard, Bonus roll and interface color (0.1.13)

New:
- First-time setup wizard: 8 steps (layout, characters shown at once,
  scale, color, accounts, announcements, bosses, columns) plus a summary.
  It keeps showing up until you finish it, picks up where you left off,
  and never opens in combat. /ggsetup opens it any time.
- Bonus roll tab: a record of your rolls with Log and Details views,
  filters by content, difficulty and character, and a per-boss detail.
- Vault tab: Pending / Claimed this week sections, showing the claimed
  reward with its date and time.
- Choose the interface color (swatches, your class color or any color).
  Colors that mean something (Ready, Claimed, Saved, Mythic+...) stay
  fixed so they are never confused with the interface color.
- Settings > Window: rows or columns, characters shown at once, scale
  with - / +, opacity, lock position, close with Esc, center the window
  and open on the last tab used. "Save characters from level" with
  90 / 80+ / any level.

Redesign:
- Real tabs and a context bar; the window sizes itself to fit your
  characters.
- Table with column groups; columns mode with section bands.
- Raid: segmented selectors, summary boxes that jump to their group,
  boss portraits showing how many killed each boss, a scrollbar.
- Settings: ON/OFF switches, options grouped in boxes, a menu with icons
  and "Reset section".
- The character you are playing is highlighted only in its own cell,
  without covering its data.

Fixes:
- Vault: the reward details were lost within the same session.
- Bonus roll: rolls did not always reach your other account.
