improvement(docs): inherit the platform border and font-weight scales (#6252)

* improvement(docs): inherit the platform border and font-weight scales

#6241 consolidated the app's neutral border tokens and flattened its
font-weight scale. `apps/docs` was carrying an untouched copy of the
pre-migration values, so the two have visibly drifted — the docs `@theme`
block already declares it "mirrors apps/sim/tailwind.config.ts", so the
drift is against stated intent rather than a deliberate divergence.

Borders — same consolidation as the app:
- `--border` #dedede -> #d8d8d8 (light), #333333 -> #444444 (dark)
- `--border-1` and `--border-muted` become aliases of `--border`, so the 19
  existing `var(--border-1)` consumers pick up the unified colour without
  being touched
- `--divider` is retired; its single consumer moves to `--border`

Font weights — the arbitrary values the app dropped:
- `font-[480]`/`font-[470]`/`font-[500]` -> `font-medium`, `font-[430]` ->
  `font-normal`, `font-[600]` -> `font-semibold`

The navbar's active tab and its invisible width-reserving ghost both used
`font-[480]`; they move to `font-medium` together, so the anti-layout-shift
trick still holds.

Deliberately NOT ported: the app's `--border-width` hairline (0.5px on hi-dpi).
The app wires it through `borderWidth.DEFAULT` in a Tailwind v3 JS config; docs
is Tailwind v4 CSS-first, which hardcodes `border: 1px` in the utility with no
theme key, so matching it means overriding a Tailwind utility. That is a
site-wide visual change and wants its own PR with visual review.

Also unchanged: the inline SVGs. `components/icons.tsx` (328) is the brand and
integration set, `sim-logo` is a brand mark, and the handful of remaining
shapes are bespoke and positioned by hand. Docs already consumes
`@sim/emcn/icons` in the 15 places where a shared icon is the right call, and
imports zero lucide.

* improvement(docs): finish the platform token sweep

Follow-on within the same PR. A full comparison of every custom token docs
rolls against the platform found three more classes of drift.

Text scale — #6241 retuned these and docs kept the old values:
- `--text-body` #3b3b3b -> #434343 (light), #cdcdcd -> #c1c1c1 (dark)
- `--text-muted` #707070 -> #7a7a7a (light), #787878 -> #6e6e6e (dark)
- `--text-icon`  #525252 -> #5a5a5a (light), #a0a0a0 -> #969696 (dark)

Docs and the app now agree on all 62 shared token names, with zero divergent
values.

Missing shared-component tokens. Docs renders `@sim/emcn` (Badge, Chip,
ChipLink) and `@sim/workflow-renderer` (block, subflow and note views), but
never defined 14 of the tokens those components reference — an undefined
`var()` silently falls back to `currentColor`, so the failure is invisible
until the branch that uses it renders. Several are live: `--warning` on an
edited subflow, `--caution` on inline code inside a note, `--text-placeholder`
on an empty note, `--border-success` on a successful run edge. Added with the
app's values, along with `--text-icon-muted` (new in #6241) and the four Badge
palettes docs lacked (teal, cyan, pink, blue-secondary), so any variant renders
correctly rather than being one prop away from black.

Type scale — docs declares micro/xs/caption/small/base/md in `@theme` but 20
call sites bypassed it with identical raw values (`text-[13px]`,
`text-[0.8125rem]`, `text-[12px]`, `text-[15px]`, `text-[10px]`). Each now uses
the token; every value is byte-identical, so this is a rename, not a restyle.
The class reordering in the same files is biome's `useSortedClasses` reacting
to the rename — verified as a pure permutation, with the class multiset
unchanged in every file.

Deliberately left alone:
- `#33C482` / `#2FB3FF` — brand-mark SVG fills and default props in demo data,
  not styling.
- The Ask AI button's inverted `#383838`/`#575757`/`#e0e0e0`/`#cfcfcf`. The
  platform's `--surface-inverted`/`--surface-inverted-hover` hold *different*
  values, so adopting them would restyle the control rather than tokenize it.
  Worth doing, but as a visual change with review.
