Fix reactive min/max dates, modal loading, time input, and year picker

[coolsam726]

Summary

• [Bug]: Dynamic changing of the minDate and maxDate not working #96 — Reactive minDate/maxDate: mirror Filament's wire:key + hidden constraint inputs so the picker re-inits when closures re-evaluate
• [Bug]: When i disable create and edit pages on a resource and use modal for creating and editing, the field sometimes failed to load. #129 — Modal loading: expand x-load triggers, add IntersectionObserver, and listen for modal open events before initializing Flatpickr
• [Bug]: Time picker not updated after close #104 — Manual time entry: commit parsed values on onClose and input blur when allowInput or time picker is enabled
• [Ask]: Year picker #53 — Add yearPicker() with Y format and JS year extraction on change

Also closes issues already fixed in #143 that remain open on GitHub: #100, #103, #122, #126, #128, #131, #133, #141, #130, #125, #119.

Out of scope: #124 (Filament v3) — package targets Filament v4/v5 per README.

Test plan

• vendor/bin/pint --test
• vendor/bin/phpstan analyse
• vendor/bin/pest --ci (19 tests)
• npm run build
• CI matrix passes
• Manual QA: reactive min/max between two Flatpickr fields, modal create/edit form, manual time entry, year picker
