refactor: eliminate remaining 15 any warnings and ratchet rule to error

- TaskCard: four catch((err: any) => err.message) promise handlers in
  archive/unarchive/delete/move → catch((err) => getErrorMessage(err)).
- InlineCreateCard + QuickEntryBox: .catch((err: any)) model-load handlers
  → getErrorMessage(err) with existing @fusion/core import.
- TerminalModal: drop (navigator as any).maxTouchPoints — modern lib.dom
  types already expose the property.
- serve.ts: remove unused any annotation on OpenRouter model mapper; the
  array element type is already inferred from json.data.
- pi.js, runtime-resolution.ts, dashboard.ts, serve.ts, dev-server-port-
  detect.ts, devserver-manager.ts: drop now-stale eslint-disable comments
  that the cleanup made redundant.

Fix a prompt-builder regression surfaced by agent's `any` cleanup: toolCall
with a raw string `arguments` field must be preserved verbatim (JSON-quoted)
rather than coerced to `{}`; restores a previously-passing test.

Then promote @typescript-eslint/no-explicit-any from warn → error. Future
new anys must either come with a one-line disable + justification or use a
real type. Workspace is now lint-clean (0 problems).
