build(deps): bump tzlocal from 5.2 to 5.4.4 in /flask-server

[dependabot]

Bumps tzlocal from 5.2 to 5.4.4.

Changelog

Sourced from tzlocal's changelog.

5.4.4 (2026-06-29)

• Improved handling if you have a syntax error in /etc/clock.

5.4.3 (2026-06-17)

• Moved the tests back, removed the ones that check for symlinks. See issue #146

5.4.2 (2026-06-16)

• [Yanked for distribution issues]

5.4.1 (2026-06-16)

• [Yanked for distribution issues]

5.4 (2026-06-15)

• Open files with Zone names as ascii.

• Moved tests under tzlocal/tests and include them in distributions.

• Dropped support for Python 3.9 and added support for 3.14.

5.3.1 (2025-03-05)

• Now only warns bout /etc/timezone if it is actually conflicting with other timezone configurations.

5.3 (2025-02-13)

• Now supports Python 3.9 to 3.13, and no longer requires backports.zoneinfo.

• Some distributions are for some reason removing support for /etc/timezone, which is bad, because that's the only place where the timezone is stated in plain text, and what's worse, they don't delete it. So we can't trust it now, so when we have multiple configs, we are forced to just ignore it.

• Attempts to return a ZoneInfo object also for UTC.
