build: update base tsconfig rules

[BhumikP]

What

This PR includes strict type checking by adding some rules in tsconfig.base.json

 "noFallthroughCasesInSwitch": true, // pevents execution from falling through to the next case in a switch without an explicit break
 "noUnusedParameters": true,   // Throws an error if a function parameter is declared but never used.
 "noUnusedLocals": true, // Throws an error if a local variable is declared but never used.
 "strictFunctionTypes": true, //   Enforces stricter type checking for function parameters and return types to prevent unsafe assignments.

A single nitpick

Only change in c1a7f1f was formatting the compilerOptions (per the TS spec), no changes to properties.
