Align ColumnControl search controls under Quarto Bootstrap theme

[Copilot]

When rendering itables in Quarto with Bootstrap enabled, columnControl search dropdown controls can wrap unexpectedly, which misaligns the search icon/select pair and breaks the date/search control layout. This PR applies a narrow CSS override so ColumnControl search controls keep a single-row layout in Bootstrap contexts.

• CSS: prevent ColumnControl search-row wrapping

  • Updated packages/dt_for_itables/src/index.css with a targeted rule for ColumnControl dropdown search containers:

  div.dtcc-dropdown div.dtcc-search > div {
      flex-wrap: nowrap;
  }

  • Scope is intentionally limited to ColumnControl dropdown search rows to avoid side effects on other DataTables UI elements.

• Regression guard for future CSS updates

  • Extended packages/dt_for_itables/test_index_css.py with an assertion that this rule remains present in the source CSS.
  • Keeps this Bootstrap/Quarto compatibility fix from being removed during future stylesheet edits.
