Add unit tests for amRviz package (utilities, data loading, plots, UI, network, annotations)

[eboyer221]

Summary

Adds ~150 unit tests across 13 test files.

• Branch was rebased onto main after PR Package name change from amRshiny to amRviz + New Visualizations #20 merged. All amRshiny → amRviz package references in test files were updated.
• One test (makeFeatureImportTable adds hyperlinks for COG column) was adjusted from using COG_name to COG, matching where PR Package name change from amRshiny to amRviz + New Visualizations #20 actually attaches the NCBI link.
• No changes to package source code; tests only.

Test plan

1. Open R in the package root directory and run the test suite:

   devtools::test()
   

You should see output ending with approximately [ FAIL 0 | WARN 3 | SKIP 1 | PASS 150 ]. The 1 skip is the interactive-only app launch test. The 3 warnings are pre-existing tidyselect deprecations in PR #20's implementation code (in enrich_with_annotations and makeCogBarChart), not caused by these tests.
