feat: added total playlist duration

[aaryansinhaa]

Added Playlist duration;

• Used video_channels to store duration of each video in seconds, used an aggregator and added it to the schema of the playlist.
• Displayed that view in the PlaylistView component and PlaylistPanel component.

I have modified the testcases in the integration_tests and have locally tested. All test cases were passed

Please see the screenshots of the modification in UI for your reference

[benoit74]

Thank you! See inline comments.

Also please do not replace yarn with npm (do not delete yarn.lock and add package-lock.json) ; this needs to be discussed first in a separate issue (and I'm not convinced about the move yet)

And please add an entry to CHANGELOG.md in the "Unreleased" section

[aaryansinhaa]

Hey @benoit74 , really sorry for such a sloppy PR before, I have fixed and refactored my code.

I believe that the error was because I did not update the cyprus tests for zimui, will fix it asap, sorry for inconvenience.

[benoit74]

You also have to fix the QA job: run black, ruff and pyright.

Never mind about the integration tests issue, it is a false error only linked to the fact the PR originates from a fork.

[benoit74]

Code LGTM. Please squash your commits and rebase to have only one commit on top of latest commit of openzim:main branch and I will merge. We don't want merge commits from main branch to feature branch, it is just a mess in Git. I will merge after that.

@benoit74 done!

[aaryansinhaa]

Hey @benoit74 , just wanted to check in, since this PR been open for a while.
Let me know if there are any concerns or changes needed from my side.

[kelson42]

@aaryansinhaa Sorry for the lack on feedback on our side. For the moment @benoit74 is not available, but we don't forget you and he will be back worse case early February to share a feedback.

[benoit74]

Sorry for all the time and back-and-forth it took to complete this relatively small PR, not really the kind of experience we wanna give to contributors.

At least now we are good, thank you!

[cheznewa]

Thank You Very Much!
