[4.x] Add LogTenancyBootstrapper

[lukinovec]

This PR adds the LogTenancyBootstrapper to provide tenant-specific logging configuration. The bootstrapper automatically configures storage path channels to use tenant-specific directories (NOTE: for this to work correctly, the bootstrapper has to run AFTER FilesystemTenancyBootstrapper, otherwise, the logs still won't be separated) and supports custom channel overrides for custom logging scenarios (e.g. the slack channel, see the bootstrapper's comments).

Note that the bootstrapper first modifies the channel config, then forgets the channel so that on the next logging attempt, the channel is re-resolved with the modified config. Otherwise, the channel would just use the initial config (in most cases). When using a channel stack, the stack channel itself also has to be forgotten, since the LogManager could retain e.g. the original stack channel's webhook URL, while the underlying slack channel would use the updated one, and while logging, the app would actually use the initial webhook URL instead of the updated one -- encountered this very specific issue while testing).

Also, note: adding 'attachment' => 'false' to the slack channel's config makes the slack channel work with Discord webhooks (just a cool thing we figured out whlle testing the bootstrapper).

• The test relies on catching exceptions to verify webhook URLs, but this approach is fragile and may not work reliably across different environments or Laravel versions. Consider mocking the HTTP client or using a more deterministic testing approach.
