refactor(ui): sweep text-[10-13px] arbitrary sizes onto the mg-type-* scale

[JSONbored]

Summary

Follow-up to #8053 (the caption/data type-scale tokens). Sweeps every text-[10px]/[11px]/[12px]/[13px] site across both packages onto the new .mg-type-caption/-caption-lg/-data/-data-sm utilities.

Conversion rules

• text-[12px] → mg-type-caption, text-[13px] → mg-type-caption-lg — unconditional, both packages. Neither utility touches font-family, so any existing font-mono class on the same element stays valid and unaffected.
• text-[10px]/[11px] → mg-type-data-sm/mg-type-data — only where font-mono co-occurs on the same class string (the mono-context detection the issue's classification pass calls for). The now-redundant font-mono utility is dropped since the token already sets that font-family.
• text-[10px]/[11px] without font-mono — left untouched. No token in this scale covers a sans 10/11px tier; forcing them into caption (a size up) or data/data-sm (which would wrongly switch them to mono) would both be real visual regressions. This is the issue's own "genuine exception" bucket — the warn-tier guardrail from feat(ui): author the caption/data type-scale tier (batch 1 of #7844) #8053 still flags these as a residual worklist, same convention every other token rule in this codebase already uses.

Result

• apps/ui bare-arbitrary-text-size warnings: 1,181 → 301 (-74.5%, past the issue's ≥60% target)
• packages/ui-kit: 52 → 44
• text-[12px]/text-[13px] count: 0 outside documented exceptions (there are none — both sizes convert unconditionally)

Verification

• tsc --noEmit clean in both packages
• eslint . (full package) — 0 errors in both
• prettier --check . clean (37 files needed a targeted --write after the sweep shortened lines enough to change wrapping — no semantic changes, pure reformat)
• vitest run — 191 files / 1465 tests in apps/ui, 16 files / 88 tests in ui-kit, all passing
• packages/ui-kit rebuilt (dist/index.{js,cjs,css})
• Live preview: getComputedStyle confirms all four mg-type-* classes resolve to their intended font-size/line-height/font-family on real rendered content (a subnet detail page); visual spot-check showed no layout regression

Closes #7844
