refactor(console): phase 5b — decompose toolbar/input/commands-popup methods

Finish the thin-view pass on the remaining large render methods (pure code
motion, no behavior change):

- renderToolbar (225 -> 99 lines): extracted drawToolbarStatus(), the
  drawLogFilterToggles() checkbox group, drawFilterInput(), and drawZoomControls().
- renderInput: factored the command echo + built-in interception + submit into
  submitConsoleCommand(exec, cmd) -> bool, leaving renderInput to own just the
  glass panel + InputText + completion/history callback.
- renderCommandsPopup (194 -> 135 lines): removed the duplicated lowercase-and-
  find filter logic (match-count loop and per-row filter now share
  consoleCommandMatchesFilter()) and extracted the [optional]-param dimming loop
  into drawConsoleCommandParams().

Full-node + lite build clean; ctest green; source hygiene clean.
