Subject: z2: HTTP report query aliases and Gemtext Content-Type

Accept Category, Metric, and OutputFormat as alternate query keys
alongside category, metric, output-format. Serve Gemtext reports
with text/gemini; assert Content-Type in daemon tests.

Builds on y2 daemon GET /report reusing ParseReportQuery and
WriteReports.
