This generalizes and factors out some backend code so it can also be used for series and playlists. It also replaces the cursor based pagination with an offset based one. That simplifies a lot of things and allows us to get rid of a bunch of code. The frontend now uses a `page` url parameter to signify the current page. When entered manually, there are some checks and logic to make sure it's always in bounds, i.e. using a number smaller than 0 will always redirect to `page=1` and a number larger that the max number of pages will redirect to the last page. Please note that the generalization of the sorting columns will be done in a later commit.
This factors out most of the table code for re-use with other assets, namely series and playlists. Please note that the generalization of column sorting and display will be done in later commits.
This includes: (a) Backend code that allows generating custom enums for different sorting columns, trying to minimize the necessity of code duplication (b) Frontend code mostly related to parsing the custom sorting columns from URL parameters and passing these to the API Generalization of the table, to represent these custom columns will be done in the next commit.
This will now take any custom columns into consideration and makes their declaration easier while trying to limit duplicated code as much as possible without adding too much complexity. Tables now have a __somewhat__ clear and fixed stucture. Any customization, including additional columns, can be done in the respective `index` files of the asset. This is assuming that all asset tables have thumbnails, titles and descriptions that share at least some portion of their styling. But they can also be further customized. All of this is also in preparation for adding a playlist table later on. Adding that should be pretty straightforward now.
Todo: delete the other commit.
This combines two things:
(a) It fixes the event query for the `My videos` table.
Adjumstments became necessary after some upstream
changes to the series column in the `from_db` impl
of authorized events.
(b) It moves some table specific query customizations
from the generic `load_writable_for_user` function
to the impls of the `LoadableAsset` trait.
This generalizes the `Nav` and `Details` code that was used for videos, and repurposes it for series as well. With these changes, it should also be fairly easy to add this for playlists later on.
This required a bunch of changes: - The `update_acl` endpoint which talks to Opencast was generalized to work for both events and series, as their acl `put` endpoints pretty much work the same. - The access page of events was refactored and most code is now usable for both events and series. This tries to walk the thin line between modularity and overspecialization by attempting to balance out reusablility and complexity, limiting both duplicated code and prop drilling.
This adds: - a function to send a `create` request to Opencast - the graphQL endpoint to call that function from the frontend The function needs to be given ACL and a title as parameters, and can be given a description. It then constructs the metadata json that is expected by the Opencast endpoint and appends this and the serialized ACL information. The Opencast endpoint returns a new Opencast ID for the series, which in conjunction with the title and ACL can be used to "prefigure" the series in Tobira. Doing so allows a new series entry to be shown in the "My series" table without having to wait for sync.
This route features an interface with can be used to configure title, description and ACL for a new series and create said series using the API endpoint from the previous commit.

Step 3 in adding features for proper series management.
This adds a new page and UI to create a series in Tobira and Opencast.
The UI allows setting title, description and ACL for the series.
