Item 2 of #100, following the #93/#95 pattern (ToNameLookup: OrdinalIgnoreCase,
first wins, never throws):
- Overwrite child sync matches template attributes, alarms, scripts and native
alarm sources, and external-system methods, case-insensitively, like their
(parent, Name) unique indexes under SQL Server's collation. A member that
differs only in case is updated in place instead of deleted and re-added
(which lost the row id and could collide with the unique index).
- ResolveAlarmScriptLinksAsync resolves the alarm and its on-trigger script
case-insensitively; AlarmsEqual compares the script name the same way.
- ArtifactDiff (preview) matches child collections case-insensitively so it
agrees with the sync; notification recipients keep the ordinal match (no
unique index, replaced wholesale).
- The rewire passes found the template a DTO was imported onto with an
ordinal index. Since #93 an Overwrite can match a differently-cased target and
keeps its spelling, so the passes silently skipped it and the alarm on-trigger
links the sync had cleared stayed null. TryGetImported adds a case-insensitive
(base-first) fallback; composed/base template references keep the exact
lookup (item 1 of #100 is still undecided).
Test: ImportNameLookupTests.Members_inside_a_record_match_case_insensitively,
over a proxy that gives the by-name template reads SQL Server's collation.

- Preview matches template folders, shared scripts, external systems, SMTP
(by Host) and SMS (by AccountSid) with the #93 ToNameLookup comparer
(OrdinalIgnoreCase, first wins, never throws), matching SQL Server's
case-insensitive collation, so a differently-cased target row is reported as
a conflict instead of New.
- Apply-side in-memory lookups do the same: ApplyTemplateFoldersAsync, the
template folder-id map, ResolveFolderParentEdgesAsync, ApplySmtpConfigsAsync
and ApplySmsConfigsAsync. An Overwrite now updates the existing row instead of
adding a duplicate (folder names are only unique per parent, so the old
ToDictionary could also throw).
- New ITemplateEngineRepository.GetBaseTemplatesWithChildrenAsync filters
IsDerived in SQL. Preview and the Overwrite load in ApplyTemplatesAsync use it,
so a derived slot template that shares a bundled name is never the import
target. GetTemplatesWithChildrenAsync is unchanged for the id-keyed callers
(export closure, rewire passes), which can need derived rows.

- ApplyTemplatesAsync/PreviewAsync template lookups use a case-insensitive,
never-throwing comparer (SQL Server collation); base template wins over derived.
Base names are already unique case-insensitively via the filtered unique index
on Template.Name, derived templates are not covered by it.
- Preview reads database connections, notification lists and API methods with one
GetAll query each instead of one by-name query per bundled row.
- Component-TemplateEngine.md: the flattener does not call GetAllTemplatesAsync;
it loads chains via GetTemplateWithChildrenAsync.
