Standardize batch correction figure behavior across function calls

[phoman14]

Changes

• Install CCBR/MOSuite from the FigOutSync branch during setup and sync the vendored code/MOSuite package to the same updated batch_correct_counts() figure behavior before the next released image/package update.
• Load the vendored /code/MOSuite package at runtime with devtools::load_all('/code/MOSuite'), matching capsules where the package code is available in code/MOSuite.
• Expose the updated batch correction PCA, histogram, correlation heatmap, interactive plot, sample rename, and color controls in both the CLI and Code Ocean app panel.
• Use the hardcoded MOSuite color palette as the capsule default so package and capsule figure defaults stay aligned.
• Keep the CLI compatible with older installed MOSuite versions by forwarding new plotting arguments only when batch_correct_counts() supports them.
• Add tests for the FigOutSync package install, updated CLI arguments, and app panel parameters.
• Add @phoman14 attribution to the development changelog entries for this PR.
