fix(tests): add missing Sentry mock event fields across 14 spec files; fix test:coverage semicolon

`@sentry/sveltekit` wraps load functions and reads `event.request.method` and
`event.url.pathname`. Mock events that omitted `request` or `url` threw
`TypeError: Cannot read properties of undefined` on every invocation, silently
masking 86 test failures on main.

Two root causes fixed:
- Added `request: new Request(...)` (and `url: new URL(...)` where absent) to
  all mock event objects in 14 `*.server.spec.ts` files
- Changed `;` to `&&` in the `test:coverage` npm script so a failing server
  run propagates its exit code instead of being swallowed by the client run

All 576 server-project tests now pass.
