style: sidebar UX polish — unified dividers, letter-spacing, contrast, font floor

- Unify sidebar dividers: one dashed style + --sidebar-rule token (replaces 4 old tokens)
- Remove total-line border from invoice/value/summary groups (keep monthly only)
- Add --text-spacing-money: 0.05em token (was hardcoded 0.02em) for price readability
- Bump 6 font sizes from 8-10px to 0.6875rem (11px minimum floor)
- Darken --muted: Dark #9e9588→#b0a99f (6.6:1), Light #6a6157→#554e46 (6.5:1)
- Remove opacity on 9 text elements that were double-muting with --muted color
- Normalize divider weight across themes: Dark/Light 75%, Glass 0.16
