Bundles the session's UI work (the touched files carry several of these changes together, so they are committed as one coherent UI batch): - FAQ: new RenderFaqDialog + data-driven faq_content, opened from a status-bar "?" (and the Windows title bar), styled like the Wallets modal with search, Wallet/Daemon tabs, and smooth scroll. - DPI/font-scale audit: multiply hand-drawn absolute geometry by Layout::dpiScale() across ~30 files so nothing renders native-size at HiDPI / font_scale 1.5 (verified with a full sweep at 1.5x). - Mining: chart now fills the horizontal space; thread stepper +/- buttons match the input-box height; move the stratum-host toggle into Node & Security (v1.3.0+). - Settings: fix the auto-shield status text overlapping the grid. - Sidebar: drop the peer-count badge on the Network button. - i18n: wrap 193 hardcoded literals with TR() (keys/translations added in the preceding i18n commit), so the security/PIN/lock flow, seed-backup wizard, and witness-rebuild dialog localize.
