refactor: replace hand-rolled utilities and dead code with the shared forms

Each of these has a mandated helper or an established accessor in the repo that
the site predates or missed. All are behavior-preserving:

- `omit()` for the three `Object.fromEntries(Object.entries(x).filter(...))`
  block-input filters, which also recovers the `Omit<T, K>` typing that
  `Object.fromEntries` erases to an index signature.
- `getErrorMessage()` for the inline `instanceof Error` message ternary.
- `getBlock()` for two `getAllBlocks().find((b) => b.type === x)` scans, one of
  them inside a loop over selected tools. The same file already resolves the
  same values through `getBlock`.
- A memoised `Map` for three `.find()`-by-id scans over the workspace skill
  list, one of them inside a render `.map()`.
- `SELECTOR_SEARCH_STALE` for three copy-pasted `15 * 1000` literals. They are
  deliberately shorter than `SELECTOR_STALE`, so this is a new named constant
  rather than a fold into the existing one.
- Tailwind classes for the static half of two duplicated anchor styles, keeping
  only the genuinely dynamic `left`/`top` inline.
- Dropped the unused `catch` bindings on three intentional JSON-parse swallows.

`panel.tsx`'s run-button gate loses a `TODO`-stubbed `hasValidationErrors =
false` and the `isWorkflowBlocked` term built on it. That term was dead twice
over: it reduced to `isExecuting`, and the enclosing expression is already
guarded by `!isExecuting`.
