Move body-text muted callers to the semantic token

A handful of helper texts, descriptions, and side counts used
text-slate-500 directly, so they didn't pick up the contrast fix in
e4f38d5. Switch each body-text caller to text-muted: AI settings
dialog helper text, AI provider helper text and link rows, ResourcePicker
empty-state copy / resource IDs / "+N more tags" / "N selected" footer,
AIModelSelectionSection "(loading...)" tag, ConfiguredNodeTables cluster
node count, and the PatrolIntelligenceHeader plan-restriction note.

Live contrast measurement after the change: every visible muted-style
text on the Patrol page now reads between 6.92 and 7.58 on its
resolved background — well above the WCAG AA 4.5 floor it was missing
on bg-surface-alt.

Icon-tint usages of text-slate-500 (Lucide icons, chevron rotations,
hover-state controls) are left as-is — those are deliberate color
choices, not muted-text intent.
