fix(baseline): restore browser resolve conditions + fix onDelete handler type

4ca532b accidentally dropped vitest.config.ts browser resolve conditions,
environmentMatchGlobs, and hot:false — causing job-error-line.test.ts to
mount against svelte/index-server.js and fail with lifecycle_function_unavailable.
Also fixes JobErrorLine.svelte line 45: onDelete passed directly as onclick
is typed (jobId:string)=>void, not MouseEventHandler — wrap to match handler
signature, consistent with the failed-branch delete button already there.
