Improve pickers, responsive shell & sidebar UI

Refactor the editor and career pages into a responsive app shell with a nav drawer and scrim; add accessible profile/save picker overlays with backdrop, centered positioning, keyboard support, selection state, grouped save sections and empty states. Implement dropdown positioning, resize/scroll syncing, ESC/interaction-driven closing (including nav drawer auto-close), and various UI quality-of-life updates (picker icons, check state, dropdown item bindings). Update global CSS: spacing tokens, scroll masking, hide native scrollbars, header/sidebar layout and other style adjustments. Also update bundled app metadata (version string changes in Cargo.toml, Cargo.lock and tauri.conf.json) and include updated app.sqlite binaries.
