Diego Rodrigues de Sa e Souza a95da4a902 feat(routing): wire interceptFetch tool interception into the chat pipeline (#7339) (#7736)
Phases 3-4 of #3384 (Phases 1-2 shipped DB schema + resolveInterceptSearch in
release/v3.8.47). Adds resolveInterceptFetch(provider, model) as a structural
twin of resolveInterceptSearch, and open-sse/services/webFetchInterception.ts
(mirroring webSearchFallback.ts) to rewrite a provider-native web_fetch tool
declaration into a synthetic omniroute_web_fetch function tool. The synthetic
tool call is dispatched through the existing handleToolCallExecution path
(same as omniroute_web_search) to a new web_fetch builtin skill handler that
resolves credentials and calls handleWebFetch() against /v1/web/fetch.

Strictly opt-in: with no interceptFetch DB row configured (the default), the
outgoing request body is byte-identical to pre-change behavior — no heuristic
default bypass like the interceptSearch sibling, to guarantee zero overhead
when disabled (Hard Rule #20).

Also ships the dashboard toggle (owner decision, overriding the plan's
backend-only recommendation): ProviderInterceptionSection.tsx on the provider
detail page, backed by GET/PUT/DELETE /api/providers/[id]/interception-rules,
covering both interceptSearch and interceptFetch from one control.

chatCore.ts touch is minimal (frozen file): one resolver call + one
prepareWebFetchFallbackBody call mirroring the existing interceptSearch block,
plus threading provider/model into the existing handleToolCallExecution call.
