Update ESLint configuration, Dockerfile, and package dependencies; refactor bot trigger logic

- Updated ESLint configuration to use TypeScript project references and adjusted parser options.
- Modified Dockerfile to include OpenSSL in both builder and final stages.
- Changed `mime` package version from `^4.0.6` to `^3.0.0` in `package.json` and updated TypeScript ESLint packages to `^6.21.0`.
- Refactored `findBotByTrigger` function to remove unnecessary settings repository parameter.
- Adjusted bot trigger logic in multiple controller files to streamline function calls.
