feat: Refactor form sync to run as a background job with retry

[AIlkiv]

issue: #2165 , #2067

I implemented a logic to synchronize the form with the file, allowing multiple attempts if the first one fails. The process runs in the background with delays, ensuring it does not impact the user experience.

Added a fix for the issue described in #2067

Looks good to me :) I'd like to wait with the merging for @susnux's review

thanks for this PR, we can also do a backport to stable4, but you'll need to adjust the ApiController part there manually because of the duplicated routes.

/backport to stable4

[Chartman123]

The Codecov upload error isn't specific to Forms: codecov/codecov-action#1643

[susnux]

I am not sure we need the max attempts, but otheriwse fine with me.

Please fix the code style in the constructor

@susnux @Chartman123 I did requested changes. All pipelines are green except 2: PHPUnit SQLite + coverage upload. But tests pass

[Chartman123]

Might be because you made changes on a branch in a fork that doesn't belong to you. It could also help to rebase to current main

[Koc]

Already did by using Github UI button 🤷‍♂️

[susnux]

It is only the codecov action that is broken for forks, tests are fine

The codecov action was updated but they changed the syntax and we forgot to adjust it.
Let me fix that 🙈

[Koc]

pipeline is completely green now ✔️

The backport to stable4 failed. Please do this backport manually.

# Switch to the target branch and update it
git checkout stable4
git pull origin stable4

# Create the new backport branch
git checkout -b backport/2408/stable4

# Cherry pick the change from the commit sha1 of the change against the default branch
# This might cause conflicts, resolve them
git cherry-pick 10047d28

# Push the cherry pick commit to the remote repository and open a pull request
git push origin backport/2408/stable4

Error: Failed to cherry pick commits: error: no cherry-pick or revert in progress
fatal: cherry-pick failed

I will take care about backport to stable4 later today

[Chartman123]

Nice, thank you :)
