refactor: flatten and reduce tsconfigs

[jackkav]

Motivation:

inso architecture is tangled and complex
build and type-checking parameters are merged and inherited and confusing
inspired by https://www.totaltypescript.com/tsconfig-cheat-sheet
aiming to flatten and make specific the tsconfigs required to type-check and build the inso cli
The eventual goal is to make the inso build process easier to maintain by removing steps or simplifying them
This PR could also affect type-checking in the app, but the worthy subgoal is for it to be easier to modify tsconfigs to add strictness

• removed type check in build:sr
• removed tsconfig.build.json
• grouped tsconfig options
• removed unused lines in package.json and tsconfig.json

future work

• add more strictness to tsconfig with verbatimModuleSyntax (#7718), noUncheckedIndexedAccess
