resolve (shared by Check/Apply) and Apply now wrap GetRecords/ApplyChanges
failures in service.ErrProviderUnavailable, matching ZoneRecords' existing
behavior. handleApply/handleCheck use errors.Is against it to return 502
with the real provider message (e.g. Selectel's 409 conflict body) instead
of masking every failure as a generic 500 "internal error"; non-provider
errors (decrypt/db/loader) are unaffected.

RecordDiff.Key() gives a stable normalized identifier ("TYPE name.") for
every diff kind, exposed as recordView.Key. ApplyRequest now takes
Updates/Prunes key lists instead of two booleans, so callers can apply a
subset of records. service.Apply builds the applied set with selected
prunes (Delete) added before selected updates (Add/Update) — an
invariant, not an option — since the provider rejects an Add/Update
whose name still conflicts with an existing record (e.g. a CNAME cannot
be created while an A on the same name still exists).

Adds internal/tmpl with Materialize (template placeholder -> zone name) and
Parameterize (zone name -> placeholder, the inverse used by the
template-from-zone snapshot). service.resolve now materializes the template
against DomainRef.ZoneName before diffing, so one template can be reused
across domains. LoadDomainFull (source query + hand-edited sqlc output, since
sqlc is not installed) now also selects zone_name to populate it.

Introduce service.ErrProviderUnavailable, wrapped only around the
provider GetRecords call in ZoneRecords. handleZoneRecords and
handleTemplateFromZone now use errors.Is against it to tell a real
provider outage (502) apart from local resolution failures such as an
unknown domain (404), instead of collapsing every ZoneRecords error
into a blanket 502. Also fixes handleTemplateFromZone's GetDomain
error branch to return 404 "domain not found" instead of 500, for
consistency with handleSetDomainTemplate/handleDomainHistory.

LoadDomain requires a template, so a zone without one could never be
viewed or snapshotted. Adds a template-free path: store.LoadZone /
service.ZoneRef / DomainService.ZoneRecords read a zone's live records
straight from the provider (no diff, no template). GET
/domains/{did}/records exposes read-only viewing; POST
/domains/{did}/template-from-zone snapshots only managed record types
(NS/SOA excluded) into a new template and auto-attaches it to the domain.
