The web server read XDG_CONFIG_HOME through a redundant typeof guard on a
value that is already string|undefined, which tripped the anti-slop lint on
its own new line and diverged from the VS Code helper. Both now read the
same way. The VS Code provider test also still hard-coded ~/.config/opencode,
so it silently stopped asserting whenever XDG_CONFIG_HOME was set; it now
uses the shared constant, like the web test already does.
The legacy `providers` block is deleted whole when its last entry migrates
to `provider`. Nothing covered the case where other legacy entries remain,
so a regression there would silently drop unrelated providers. Adds the
case to both the web server and VS Code parity suites.
Derive the effective OpenCode config layer (custom > project > user) from
provider sources and send it on PUT /api/provider so project/custom edits
update that layer instead of creating a global user override. Resolve
OPENCODE_CONFIG at call time and add UI/web/VS Code coverage for scoped
upserts.

Require an API key or {env:VAR} on client and server, add edit/prefill for
existing custom providers, save auth before config, and surface incomplete
auth plus disconnect after partial failures. Add VS Code parity tests and
drop the unused allProvidersConnected locale key.
