feat(web-test): expand alias, tree expand fix, fillTableRow checkbox support

- clickElement: add `expand` option (alias for `toggle`) for tree expand/collapse
- clickElement: fallback to dblclick when tree +/- icon not found (was NumpadAdd)
- dom.mjs: search [tree="true"] in entire line, not just first imgBox
  (fixes trees with checkbox column before tree column)
- fillTableRow: detect checkbox cells after first click, return immediately
  without escalation (dblclick/F4). Checkbox state detected via .select class
- SKILL.md: document `expand` instead of `toggle`
