The shared engine treats every panel as an ARIA menu and preventDefault'd
single-char + arrow keys, so typing in a panel with inputs (the zap
comment/amount fields) was swallowed — "you can't type in the popup".
handleMenuKeydown now ignores editable targets.
Also relocate a pre-existing in-host panel (the in-modal zap dialog) into
the body-level portal on open so position:fixed is viewport-relative
instead of anchoring to the modal edge, restoring it on close. Pure DOM
helpers extracted to popoverPanelDom.js to keep the engine under its cap.

- Exposed `HTMLStyleElement` globally in `tests/ui/popoverEngine.test.mjs` to resolve a `ReferenceError` during `instanceof` checks.
- Updated assertion in "applies token-based sizing and arrow positioning" to check the `--popover-arrow-top` CSS variable instead of the `top` property, as JSDOM does not compute layout properties from variables.
- Verified all tests in the file pass.
