Mitigate attachment/send upload issues

This PR attends to mitigate (not fix) #2644.
There seems to be an issue when uploading files either as attachment or
via send via the mobile (Android) client.

The binary data gets transfered correctly to Vaultwarden (Checked via
Wireshark), but the data is not parsed correctly for some reason.

Since the parsing is not done by Vaultwarden it self, i think we should
at least try to prevent saving the data and letting users think all
fine.

Further investigation is needed to actually fix this issue.
This is just a quick patch.

Merge branch 'update-github-actions' of https://github.com/BlackDex/vaultwarden into BlackDex-update-github-actions

The previous persistent folder check worked by checking if a file
exists. If you used a bind-mount, then this file is not there. But when
using a docker/podman volume those files are copied, and caused the
container to not start.

This change checks the `/proc/self/mountinfo` for a specific patern to
see if the data folder is persistent or not.

Fixes #2622

Because we want to support MSRV, we also need to run a CI for this.
This PR adds checks for the MSRV and rust-toolchain defined versions.

It will also run all cargo test, clippy and fmt checks no matter the outcome of the previous job.
This will help when there are multiple issues, like clippy errors and formatting.
Previously it would show only the first failed check and stopped.

It will also output a nice step summary with some details on which checks have failed.
Or it will output a success message.

Fix issue with CSP and icon redirects

When using anything else but the `internal` icon service it would
trigger an CSP block because the redirects were not allowed.

This PR fixes #2623 by dynamically adding the needed CSP strings.
This should also work with custom services.

For Google i needed to add an extra check because that does a redirect
it self to there gstatic.com domain.

Merge branch 'more-clippy-checks' of https://github.com/BlackDex/vaultwarden into BlackDex-more-clippy-checks

- Update deps. One of them is multer-rs which fixes #2516
- Changed MSRV to `1.59.0`, since that is the correct MSRV currently.
  It could be lower, but that would mean removing the `strip` option.

A bit inspired by @paolobarbolini from this commit at lettre https://github.com/lettre/lettre/pull/784 .
I added a few more clippy lints here, and fixed the resulted issues.

Overall i think this could help in preventing future issues, and maybe
even peformance problems. It also makes some code a bit more clear.

We could always add more if we want to, i left a few out which i think
arn't that huge of an issue. Some like the `unused_async` are nice,
which resulted in a few `async` removals.

Some others are maybe a bit more estatic, like `string_to_string`, but i
think it looks better to use `clone` in those cases instead of `to_string` while they already are a string.

Because apparently CLion's default formatting is not the same as rustfmt for some reason.

This is to support scenarios where the attachments and sends folder are to be stored on a separate device from the tmp_folder (i.e. fuse-mounted S3 storage), due to having the tmp_dir on the same device being undesirable.

Example being fuse-mounted S3 storage with the reasoning that because S3 basically requires a copy+delete operations to rename files, it's inefficient to rename files on device, if it's even allowed.

Add `password_hints_allowed` config option

The latest version (1.62.0) that was just released includes Clippy changes
(https://github.com/rust-lang/rust-clippy/issues/9014) that break the build.

Disabling password hints is mainly useful for admins who are concerned that
their users might provide password hints that are too revealing.
