Code clean up - tsconfig.json

Here are some ways this TypeScript config could be improved:
Specify stricter type checking
Set "strict": true, and "noImplicitReturns": true,
Enable strict null checking
Add "strictNullChecks": true, to catch more errors
Remove unneeded options:
Like "allowJs" and "noEmit" since this is a Next.js project.
Enable type checking for test files
Add to "include": ["test/**/*.ts"]
Use TS compilation incrementally
Set "incremental": true, for faster rebuilds
Add folder aliases:
"paths": { "@components/*": ["components/*"] }

Extend linting to TypeScript
Configure ESLint to run on .ts files
Specify a JS target
Like "target": "es2020",
Consider strict property initialization
"strictPropertyInitialization": false,
Scope libraries to usage
"lib": ["es2020", "dom"]

Some key principles to follow are strictness, reducing cruft, isolation, and leveraging types
