fix(reports): request changes form validation for compounds and organisms

[vcnainala]

Summary

• Fix Filament v4 Select validation in the Request Changes form so existing synonyms, CAS IDs, geo locations, organisms, and citations submit correctly ("Request changes" not working #775)
• Allow linking organisms that already exist in the database when requesting molecule changes, while still blocking organisms already attached to the target molecule (Addition on organism not working #772)
• Unblocks data curation issues where curators need to add species and citations via Request changes (e.g. Add species and citation to CNP0512695.0 #170)

Changes

• ReportResource: replace static molecule loading with resolveMolecule() / valueKeyedOptions() helpers; add hidden compound_id and type fields for Livewire persistence; use dynamic repeater schema for new organisms
• Organism: parameterize getForm() with requireUniqueName and excludedNames for report-change context
• Tests: unit coverage for option-key validation and organism name rules

Test plan

• php artisan test tests/Unit/ReportResourceMoleculeOptionsTest.php tests/Unit/OrganismReportChangeFormTest.php
• Request changes for a compound with synonyms/CAS (e.g. CNP0520383.0): rename and add synonym without validation errors
• Request changes: add an organism that exists in COCONUT but is not linked to the molecule
• Request changes: verify already-linked organism name is rejected with a clear message
• Organism admin create still rejects duplicate organism names
• After deploy: curate Add species and citation to CNP0512695.0 #170 (CNP0512695.0 — add Valeriana pavonii and Biomédica 2010 citation)
