forgejo: disable users explore page 
This was requested and should make it a decent bit more difficult to get
a somewhat complete list of users on this instance.

We are, however, aware of other endpoints that can be used to get to a
similar result. Those just aren't as convenient nor obvious.

raito 62ccc0282b fix(ows): per-job runtime directories + proper local refspec 
The local refspec was weird and exploiting a edge case for the nixpkgs
jobs where local and from were the same.

We are more explicit now, which fixes the sandbox jobs.

emily 8d2a367e92 grafana-agent: make bagel.monitoring.grafana-agent.exporters an attrset 
This allows us to use multiple jobs, one for each additional exporter,
and set their `job_name` accordingly.

`job_name` is exported as `job` label on the resulting metrics.
This allows us to quickly get an understanding what metrics of an
exporter are actually available by simply filtering all metrics by
`{job="$jobname"}`

emily db8c831c2f grafana-agent: set hostname label on all metrics 
This is handy to quickly see all metrics exported by a node, without
having to mangle with the already existing `instance` label.

`hostname` is essentially a variant of `instance` but without ports.
