feat(ui): implement UI/UX audit — i18n, HiDPI, theme, destructive-action & overflow fixes

Implements all 26 confirmed UI/UX audit findings plus the 4 dashboard/timeline
tile labels. Verified across full-node + Lite + Windows builds (ctest green) and
an adversarial diff review (one market-tab delete regression caught + fixed).

i18n coverage:
- Balance hero/quick-actions/toasts + dashboard & timeline tiles (Total Balance,
  Shielded, Transparent, Quick Send, Quick Receive, Click to open, Market)
- Send: Review Send / Cancel / Paste / view-only tooltip / memo byte counter
- Settings: Lite lifecycle errors, plaintext-RPC security warning, 8 toasts
- Mining pool-payout tooltip
- Resolve daemon_update_title double-assignment collision (new daemon_update_prompt_title)
- 23 new keys translated into all 8 locales; CJK subset font rebuilt

HiDPI: DPI-scale the Send amount bar, mining thread-tile clamp bounds, receive
loading skeleton, and sidebar notification-badge insets.

Light theme: theme-aware material::SurfaceOverlay() for balance bar tracks and
row-hover highlights; contacts active-pill foreground uses OnPrimary().

Destructive actions: arm/confirm for portfolio-group delete, saved pool/worker
remove, and avatar-image delete.

Interaction/overflow: route balance star/eye buttons and the console fold-toggle
through popup-safe guards; clip peer addr/subver; truncate the balance custom
label; measure Settings tool-button widths; mining stepper disabled-state
feedback; +/- stepper buttons restyled to match the thread tiles.
