feat: Update dependencies and enhance job run details template

- Add new dependencies: `github.com/joho/godotenv`, `github.com/stretchr/testify`, and `gopkg.in/natefinch/lumberjack.v2`
- Remove indirect dependency on `github.com/joho/godotenv`
- Refactor JobRunDetails template to separate content rendering for improved testing
- Enhance error message display in JobRunDetails template
- Introduce new test files for JWT and password functionalities
- Add comprehensive tests for database operations and error handling
