Lifetime licence support plus picker mount reliability. Adds clean handling for lifetime licences in the licence panel and ensures the picker attaches reliably inside ACF Blocks v3 inspectors.
- Lifetime Licence Support: The licence panel now recognises lifetime licences — showing "Lifetime" billing with no renewal row and "Never" for expiry, while keeping the status active.
- Picker Mount Reliability (ACF Blocks v3): Added a MutationObserver fallback that mounts picker hosts as soon as
.openicon-fieldelements appear in the DOM, independent of ACF'sready/ready_field/append_fieldactions. Resolves a case where the picker failed to attach inside Gutenberg block inspectors on certain theme / companion-plugin stacks.
