chore(deps): update python-dotenv requirement from >=1.0.0 to >=1.2.2 in /backend

[dependabot]

Updates the requirements on python-dotenv to permit the latest version.

Release notes

Sourced from python-dotenv's releases.

v1.2.2

Added

• Support for Python 3.14, including the free-threaded (3.14t) build. (#)

Changed

• The dotenv run command now forwards flags directly to the specified command by @​bbc2 in theskumar/python-dotenv#607
• Improved documentation clarity regarding override behavior and the reference page.
• Updated PyPy support to version 3.11.
• Documentation for FIFO file support.
• Support for Python 3.9.

Fixed

• Improved set_key and unset_key behavior when interacting with symlinks by @​bbc2 in #790c5
• Corrected the license specifier and added missing Python 3.14 classifiers in package metadata by @​JYOuyang in theskumar/python-dotenv#590

Breaking Changes

• dotenv.set_key and dotenv.unset_key used to follow symlinks in some situations. This is no longer the case. For that behavior to be restored in all cases, follow_symlinks=True should be used.

• In the CLI, set and unset used to follow symlinks in some situations. This is no longer the case.

• dotenv.set_key, dotenv.unset_key and the CLI commands set and unset used to reset the file mode of the modified .env file to 0o600 in some situations. This is no longer the case: The original mode of the file is now preserved. Is the file needed to be created or wasn't a regular file, mode 0o600 is used.

Misc

• skip 000 permission tests for root user by @​burnout-projects in theskumar/python-dotenv#561
• Bump actions/checkout from 5 to 6 in the github-actions group by @​dependabot[bot] in theskumar/python-dotenv#593
• Add Windows testing to CI by @​bbc2 in theskumar/python-dotenv#604
• Improve workflow efficiency with best practices by @​theskumar in theskumar/python-dotenv#609
• Remove the use of sh in tests by @​bbc2 in theskumar/python-dotenv#612

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
