5177: Debug log the channel congestion r=Kerollmops a=Kerollmops
This PR displays the congestion of the BBQueue channel and the allocated memory for the channel and the extraction. This information can be beneficial for debugging and noticing slow disks. We show three pieces of information in debug:
- The direct attempts: the number of tries to send something in the BBQueue channel,
- The blocked attempts: the number of unsuccessful attempts that must be retried,
- The congestion: The percentage of blocking attempts. The higher, the slower the receiver and, therefore, the disk.

5272: Fix Batches Deletion and flaky tests r=irevoire a=Kerollmops
- This issue fixes#5263 by removing the batches from the date and time databases.
- It also introduces a new `enqueued_at` field in the batch object to quickly retrieve them in the `batches.enqueued_at` database
- Finally, it probably fixes all the flaky tests of the batches: https://github.com/meilisearch/meilisearch/issues/5256

5289: Fix workload files after removing the vectorStore experimental feature r=Kerollmops a=dureuill
Running the bench [currently fails](https://github.com/meilisearch/meilisearch/actions/runs/12990029453) on embedding-related workloads, due to the call to `/experimental-features` that is used to enable the vector store:
In v1.13, `vectorStore` is no longer an experimental feature, so trying to enable it causes a 400

5264: Dumpless upgrade r=dureuill a=irevoire
# Pull Request
Usage: https://meilisearch.notion.site/Dumpless-upgrade-fff4b06b651f81f1acafe24d4687b3f7?pvs=74
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/5162
## What does this PR do?
- Implement the dumpless upgrade with multiple hooks:
- In meilisearch directly before the task queue has been opened
- In the index-scheduler while processing the task
- In milli while upgrading the indexes
- There is no hook at search/query time to handle the old version of a database. That's left to the next person upgrading a database
- A new special type of task (`upgradeDatabase`) that can be retried has been introduced
- A new experimental cli flag has been introduced
- The version has been upgraded to the v1.13.0 in this PR otherwise it was a lot of useless work to test the dumpless upgrade
- Multiple tests have been introduced
## PR checklist
Please check if your PR fulfills the following requirements:
- [ ] Update the issue template we use for features, mentioning what we should do in case of a database upgrade
- [ ] The experimental feature discussion should be opened and updated in the PR
- [ ] Update the PRD
- [ ] Add the new error codes
- [ ] Add the task details
- [ ] Add the telemetry
## Notes
The new tests introduced are not _that_ slow
