Manage technologies through the API, with SVG logos

/api/v1/technologies is a full CRUD with the panel's own rules: name and
slug are plain strings, the prose is translatable, `radar_ring: null`
takes one off the radar, and TechnologyPolicy still refuses to delete
one a project, member or call uses. The MCP server picks the tools up
from openapi.yaml on its own.

A logo is an SVG, so POST /v1/media now accepts one — sanitized with
enshrined/svg-sanitize (scripts, event handlers and remote references
removed), and served by Caddy under a Content-Security-Policy that
would stop a script regardless. `for` (pages or technologies) says what
an upload is for, which picks the directory the panel uses for it and
the permission it takes.

Creating a technology without a category answered 500: the column's
default never reached the model, so the response read a null enum. The
controller now states the default, as the panel does.

Beside a file, the MCP upload tool no longer demands the JSON body's
`url`: the body then carries the upload's other fields, such as `for`.
