[BUG] Timeout when saving big database (stored on WebDAV/NextCloud)

Checks

• I have read the FAQ section, searched the open issues, and still think this is a new bug.

Describe the bug you encountered:

I have an +80MByte database stored on my Nextcloud run by hetzner.com.
When I make changes and save it it runs into a timeout.
On my phone I see the upload is happing @ ~1MB/s. So its not fast I know.

Here's the log:

Describe what you expected to happen:

The http upload should not run in a timeout so quickly. Timeout should be raised or make it a setting.

What version of Keepass2Android are you using?

1.14-r4

Which version of Android are you on?

12

Start in WebDavStorage.java at uploadFile entries around lines 267 and 315, then follow the CachingFileStorage.UpdateRemoteFile path shown in the stack trace. Reproduce an upload of a large WebDAV database and determine where the timeout is applied; done means the upload no longer fails prematurely or the timeout can be configured as requested.
