Description:

                                            [IMP] viin_brain: mobile/tablet responsive - frozen-backdrop fix + context bottom-sheet

Mobile/tablet defects found by a live Playwright survey (phone 390 + tablet 768):
- BLOCKER "frozen UI" on phone: a global `.o_brain_drawer_backdrop` rule in
  brain_create_drawer.scss (pointer-events:all, z-index:1040) collided with the
  mobile sidebar backdrop of the same class, so the always-present phone backdrop
  swallowed every tap. Rename the create-drawer backdrop to a private class.
- Phone: page context menu clamped on-screen (was off the left edge); header
  actions wrap; sidebar containing-block fix; sidebar auto-closes after page nav.
- Tablet: "More" overflow menu + temporal slider + context-pane toggle handle
  kept inside the viewport.
- NEW: phone context bottom-sheet - the context pane (Graph / temporal scrubber /
  Fact History / Properties / Backlinks) was display:none on phone; now a
  bottom-sheet (FAB trigger + backdrop + drag-dismiss) makes it reachable.
All changes gated to phone/tablet media queries + isMobileViewport; desktop
(>=1024px) byte-identical.
