fix: merge proxy into project-level contextOptions

Playwright resolves project config by replacing root-level `use`
properties with project-level ones. When a project defines its own
`use.contextOptions` (e.g. reducedMotion), it completely overrides
the root-level contextOptions — losing the SC tunnel proxy settings
and causing scripted requests to fail with ENOTFOUND.

This iterates over user-defined projects and merges proxy settings
into each project's contextOptions so both coexist.

Fixes INT-11
