fix: GeneSets bug

[kaloster]

Users reported issues where:

• Gene list under GeneSets were not appearing when using Differential Expression feature
• Genes are missing from gene search

Changes:

• Updated Gene Expression logic to handle DE genesets while maintaining same functionality for user genesets
• Updated max categories to avoid omitting genes from the list - previously capped at 1000

Pull Request Overview

This PR addresses a bug in differential expression (DE) functionality by increasing the category limit and improving gene ID resolution logic. The changes focus on handling larger datasets and ensuring proper gene name/ID mapping when processing genesets.

• Increased maximum categories limit from 1,000 to 30,000 to accommodate larger datasets
• Enhanced gene ID resolution to handle cases where gene names may be stored as IDs
• Improved gene name mapping to use the correct display name for genes
