refactor(ui): consolidate raw ImGui buttons onto material::TactileButton

UI-standardization audit: ~66 call sites still used raw ImGui::Button /
ImGui::SmallButton instead of the app's canonical TactileButton, so those
buttons missed the standard glass fill + rim + tactile overlay (and the
light-theme flat treatment). Convert 59 plain action-button sites across the
wizard, security dialogs, settings, market/console/explorer tabs, and the
address dialogs to material::TactileButton / TactileSmallButton (drop-in:
same signature/return, args preserved verbatim). Danger buttons keep their
PushStyleColor wrappers — Tactile renders through them then overlays.

Deliberately left raw (not plain buttons): InvisibleButton hit-targets, the
frameless transparent-bg collapsible-header toggles (RPC/Debug), the icon-only
pagination chevrons, and the receive All/Z/T segmented filter — a glass rim
would clash with those intentionally borderless/segmented looks.
