* fix(dashboard): OAuth modal surfaces real error on non-JSON responses (port from 9router#1318)
The OAuth connect/reauth modal called `await res.json()` unconditionally, so
a non-JSON error response (e.g. a plain-text 500 page from a build/OAuth
endpoint) threw `Unexpected token 'I'...` and hid the real failure. New
shared helpers parseResponseBody / getErrorMessage (src/shared/utils/api.ts)
read the body safely (JSON when JSON, raw text otherwise) and produce a clean
message either way; every modal fetch site now uses them.

* fix(dashboard): type OAuth modal response body as Record<string, unknown> (t11 any-budget)
Switch the parseResponseBody casts from Record<string, any> to
Record<string, unknown> so OAuthModal.tsx stays within its t11 explicit-any
budget. getErrorMessage already takes unknown; the success paths typecheck
clean under strict:false. No runtime change.
