Geo: Improve HA install docs

Update docs for multi-project pipelines

Closes #209041

See merge request gitlab-org/gitlab!26560

The docs were mixing visualizations / graphs with

over different tiers. This splits visualizations into
a new section, which can be badged with it's tier,
while the rest becomes free (since 12.8).

Geo - Make registry table SSOT for Uploads

See merge request gitlab-org/gitlab!25482

FileDownloadDispatchWorker looks only at the registry table
for things that have never been synced.

In order for the counts to be correct, we have to distinguish
between "never synced" and "failed" with "retry_count" being
"nil" for the former and "not nil" for the latter.

Feature flag is "geo_file_registry_ssot_sync".
