Guilhem LemouelandClaude Opus 5 d964dfe7f6 fix(backend): say what is missing when a $res: or $var: reference does not resolve
Both interpolations fetched with fetch_one and mapped the error through to_anyhow, so a
reference to something deleted surfaced as "no rows returned by a query that expected to
return at least one row @workspaces.rs:2169". It names neither the kind of thing that was
missing nor its path, and it is what a data table pointing at a deleted resource reports.

They now fetch_optional and return NotFound naming the path, and datatable resolution adds
the data table on the way out: the caller asked for one by name, and a bare "resource
f/x/y does not exist" leaves them to work out which of them points at it. The health probe
is new, so this string had only just become something users read.
