SCRUM-5935: Add audit columns and expandable synonyms editor

[VarunReddy1111]

Summary

• Add Date Updated and Updated By columns to both Resource Descriptors and Resource Descriptor Pages tables (read-only, sortable, filterable)
• Replace single-line StringListEditor with a new StringListTextAreaEditor for synonyms editing — uses an auto-resizing textarea (5 rows default) to make it easier to read and edit entries with many synonyms (e.g., SNOMED)

Test plan

• Navigate to #/resourcedescriptors — verify Date Updated and Updated By columns appear
• Navigate to #/resourcedescriptorpages — verify Date Updated and Updated By columns appear
• Edit a Resource Descriptor row — verify synonyms field shows a multi-line textarea instead of a single-line input
• Check SNOMED prefix synonyms — verify all synonyms are readable without excessive horizontal scrolling
• Verify the textarea auto-resizes as content grows

Review

The changes look correct. A few observations:

Audit columns (Updated By / Date Updated): Both new column definitions in ResourceDescriptorsTable and ResourceDescriptorPagesTable exactly match the established pattern used across many other tables (ControlledVocabulary, Genes, Alleles, etc.). Filter configs exist and are correct.

StringListTextAreaEditor: This is a clean extraction from StringListEditor — same split/trim/filter logic, swapping InputText for InputTextarea with autoResize. The old StringListEditor remains in use by SpeciesTable, so nothing is orphaned.

No bugs, security issues, or performance concerns. LGTM.
