Count intercepted requests for mock nth - #1987

MockResponsePlugin and MockStdioResponsePlugin only advanced the nth counter when a mock was applied. Without a fallback mock for the same URL, the counter never advanced and nth mocks never fired. The counter now advances for every intercepted request matching the mock, whether or not a mock is applied.

What changed in this PR
Updates HTTP and stdin mock counting so nth advances on matching intercepted traffic, even when no mock is applied, addressing #1958.
Changes:
- Separates request matching from occurrence selection.
- Counts matching requests and messages before selecting a mock.
- Adds HTTP tests covering fallback behavior and exact/wildcard URLs.

Closes #1958
nthon mocks counted applied mocks, so without a fallback mock for the same URL the counter never advanced and thenthmock never fired.Now
MockResponsePluginandMockStdioResponsePlugincount every intercepted request/message matching the mock (method, URL, body / stdin pattern), whether or not a mock is applied. Existing setups with a fallback mock behave the same.Tests: added integration tests for
nthwith and without a fallback mock (exact and wildcard URL).DevProxy.Integration.Tests: 96/96 pass.
