Subject: [PATCH] Lower Brotli default compression level to 4

Brotli defaulted to level 11 (near-max), which is too slow for an HTTP
response path. Set a fast, HTTP-sensible default of 4 and add an
explicit Zstd default of 3. GZIP and Deflate have no public level
setter in utopia-php/compression 0.1.4, so their PHP defaults (6) are
left as-is.
