chore: speed up python integration test setup builds

Bundles four small UX fixes — three regressions from the typography
(#11199) and icons (#11222) migrations, plus the DashboardDescription
fallout from #11352:

- Widget panel title truncates to "Title..." even when the panel has
  plenty of horizontal space. The title container had no `flex: 1` /
  `min-width: 0`, so it collapsed to content width and the 80% cap
  triggered early truncation. Make the title row a real flex item.
- Variable editor "Default Value" label and helper text run together
  on one line. `Typography` from `@signozhq/ui` defaults to
  `display: inline`, so the helper text sat next to the label. Force
  block layout in the default-value-section.
- Cross-Panel Sync info icon was the outline `Info`, inconsistent with
  the `SolidInfoCircle` used everywhere else (widget header, threshold,
  status message). Swap to the standard icon at size "md".
- After #11352, DeleteButton renders as an antd `<Button>`, but the
  DashboardDescription action menu still targeted `.ant-typography`
  for the delete entry, so it picked up the list-page module's 8px /
  12px styling and went out of sync with its peers. Consolidate the
  three near-duplicate `section-1` / `section-2` / `delete-dashboard`
  blocks into a single `section .ant-btn` rule, with section dividers
  and the danger color as the only per-section overrides.
