Fix: real-hardware bring-up issues found at 1920x1080 on the Pi

After testing the V09 redesign live on the Pi at onefinity.local
(1920x1080, Chrome fullscreen) several real bugs surfaced. This
commit fixes all of them.

Layout fits at 1920x1080
- Cap .app-shell at 100vh height with overflow:hidden so child
  flex containers actually constrain to one screen.
- Make .control-page / .program-page / .console-page use
  flex 1 1 auto + min-height 0 + overflow hidden so the page total
  no longer grows to ~36 000 px when the gcode-viewer is mounted.
- Override clusterize.css default max-height: 200px on the
  .clusterize-scroll element with max-height: none + flex 1 1 0 +
  height 100% so the gcode listing fills the available column.

E-Stop in the header
- The legacy estop.pug SVG had width=130 height=130 but no
  viewBox, so CSS-only sizing did nothing and the SVG content
  spilled ~26 px off the right edge of the screen and ~70 px
  below the header. Add viewBox="0 0 130 130" plus
  preserveAspectRatio so CSS sizing actually shrinks the inner
  geometry. Drop the octagonal clip-path (the SVG already
  carries its own yellow safety ring + EMERGENCY/STOP text).

3D toolpath preview (path-viewer)
- The legacy .path-viewer.small CSS clamped the canvas to
  340 x 150 floated into the corner. In the new program-body
  grid we want it to fill the 600 px right column. Override
  with width 100%, height auto, float none, !important.
- Make orbit.js wheel/touchstart/touchmove listeners
  {passive: false} so OrbitControls.preventDefault() actually
  works and the page no longer scrolls while panning the 3D
  view on a touch screen.

Vue 1 template + reactivity bugs exposed by the live data
- Replace v-else-if (Vue 1 has no v-else-if) in
  control-view.pug with three sibling v-if templates that
  mutually exclude on w.enabled and state['2an'] == 3.
- axis-vars._get_motor_id: guard motor.axis.toLowerCase()
  against undefined motors (initial config is [{}, {}, ...]).
- axis-vars._check_is_enabled: prefer config.motors[i].axis
  when present, fall back to state[N + 'an'] only for
  recognised axes (x/y/z/a) so undefined == undefined
  doesn't mistakenly enable b/c rows.
- program-mixin: tolerate state.files / state.gcode_list
  being undefined right after connect.

App-shell race conditions
- Skip the early parse_hash() in app.js ready() when the
  initial hash is in the settings family. Those Svelte
  components read settings.units / settings.probing-prompts /
  motion.* etc. and crash on first paint with the empty
  placeholder config. Stay on loading-view until update()
  completes and routes us in itself.

Misc
- src/static/js/ui.js: null-guard the legacy burger menu code
  (#menuLink no longer exists). Was throwing 'Cannot set
  properties of null (setting onclick)'.
- src/static/css/Audiowide.css: switch the gstatic font URL
  from http:// to https:// so it isn't blocked as mixed
  content under the home.muehe.org HTTPS proxy.
- Macro buttons: drop the default 6 px yellow border-left.
  The stripe now only appears via .has-color when
  state.macros[i].color is actually configured. Removes the
  asymmetric/lopsided look from the screenshot.

Tested live on http://10.1.10.55/ and via the HTTPS proxy at
https://onefinity.home.muehe.org/.
