[FEAT] Add UI settings for schedule, servers and datetime formats

[CortanaXB]

Is this a new feature request?

• I have searched the existing issues

Wanted change

Expose the following configuration options in the Web UI:

• SPEEDTEST_SCHEDULE
• SPEEDTEST_SERVERS
• DISPLAY_TIMEZONE
• CHART_DATETIME_FORMAT
• DATETIME_FORMAT

These options currently require environment variables, but they are runtime settings that would fit well into the existing Settings page.

Reason for change

Moving these options into the UI would improve usability and make runtime configuration possible without modifying docker-compose files or recreating containers. This would also make the environment variables optional and provide a more consistent user experience for both technical and non-technical users.

Proposed code change
