fix(dashboard,ui): ConditionBlock styling (#10481)

**What**
- Resolves CMRC-58
- Also fixes some other issues, TS errors, Eslint warnings etc. in the Promotion domain. There are still several TS errors as the return types from `@medusajs/types` don't seem to match how they are used here, but I have left that as is, as I am not super familiar with the Promotion module.
