Describe the code debt
We currently have suppressImplicitAnyIndexErrors in our tsconfig.json since we have a lot of implicit any types scattered throughout our code. That option will be going away in Typescript 5.5, so we'll need to turn suppressImplicitAnyIndexErrors off, see where these errors are occurring in our code, and fix them. Typescript says the fix is to "Add an index signature to the relevant type (or use a type assertion at the indexing location)."

To Fix
Steps to fix this:

1. Remove "suppressImplicitAnyIndexErrors": true, from tsconfig.json
2. Run make
3. See what Typescript complains about
4. Fix each error location individually
