cleanup: .form-row.search-bar + .select-compact.size-md modifiers

The Archive-search tool-row carried two inline-style attrs:
- .form-row with gap:8px; margin-bottom:8px; flex-wrap:wrap; align-items:center (different rhythm from the existing .aligned / .section-header form-row modifiers — tool-row that should wrap on narrow widths)
- archiveSearchStreamer .select-compact with min-width:160px (matches the existing .form-stack.size-md width)

Extracted into two modifier classes:
- .form-row.search-bar — the search/filter tool-row pattern (search input + filter selects + go button collapse gracefully)
- .select-compact.size-md — wider select variant, mirrors the .form-stack.size-md pattern from 4.6.95 so width modifiers across element types share the same naming
