Add missing fields to ThemeVarField; add missing local-types package to base

[burieberry]

Closes CS-12721

theme.css declares 54 non---boxel-* properties; ThemeVarField covered 47. This adds the 7 missing fields and settles the status-token fallback.

Changes

• ThemeVarField: new warning color field and the six tweakcn shadow primitives (shadowX, shadowY, shadowBlur, shadowSpread, shadowOpacity, shadowColor). The primitives are stored so tweakcn themes round-trip losslessly; the composed shadow scale does not derive from them. Edit template gets rows for each; warning joins the Form & Feedback swatch group and shadowColor the Box Shadows group.
• theme.css themed-card boundary reset: --success and --warning fall back to the fixed Boxel status palette (--boxel-success, --boxel-warning) instead of initial, so a themed card that omits them still renders green/amber rather than leaking the ambient theme's value. A theme that sets them still wins.
• Number components (progress bar, progress circle, gauge, score, stat) use plain var(--success) / var(--warning); the hex fallbacks were dead once the tokens are always defined.
• packages/base loads @cardstack/local-types like every other package, so the <style scoped> augmentation applies under base's own tsconfig.

Purely additive for existing themes: unset fields emit nothing.

[Claude Code 🤖] This review chased the cascade consequences of swapping the initial sentinel for a real fallback, the tweakcn round-trip path (setCss → applyCssRulesToField → the cssVariableName lookup) that the new fields feed, and the accuracy of the new field descriptions and comments. It did not evaluate the visual design of the edit-template layout, and it did not exercise the app.

The field additions and the --boxel-*/tsconfig plumbing are sound — the token count lines up at 54 and the round-trip mechanism does what the comment says — but the theme.css boundary change reaches a consumer the description doesn't mention, and two of the new field descriptions state fallbacks that no code implements.

Recommendations, in order:

1. Decide whether BoxelSwitch losing the theme's primary is intended — see the theme.css thread. That's the one substantive behavior question; the two lines it's anchored on are also a no-op as written.
2. Correct the success / warning field descriptions — they promise fallbacks to primary/destructive that nothing implements, and they reach the assistant's card schema. See the thread on structured-theme-variables.gts.
3. Pin the round-trip with assertions in the existing setCss test — the fixture already carries all six primitives.
4. Distinguish the inert shadow primitives from the working scale in the edit UI; FieldContainer never surfaces a field description.
5. --accent as the progress 50–75% band renders #e8e8e8 under the default theme; the color-name comments no longer describe the tokens.
6. Finish or drop the partial hex-fallback sweep — it currently leaves two spellings inside one getter.
7. Dep ordering nit in packages/base/package.json.

CI is green across all 83 checks; nothing to act on there.

Adjacent, out of scope: boxel-cli/plugin/skills/boxel/references/theme-design-system.md enumerates the canonical token contract and lists neither --success nor --warning, so an assistant authoring card CSS has no reason to know they exist. Pre-existing for --success; this PR widens it by making five base components read bare var(--warning). Worth a line in that reference next time it's touched.
