Maurice 6270495327 feat(mcp): read and organise the documents on a trip
Often the travel history is the uploaded PDFs, and an assistant could not
learn that a trip had any: there was no files.mcp.ts, no files scope, and no
files section in the trip summary.

Six tools: list, read contents, set description and primary link, add a
link, remove one, list them. Reading contents rides files:content rather
than files:read, because listing what a trip carries and reading what is
inside a booking PDF are different privileges.

The content read is not a second copy of the plugin path. readContent moved
out of files.rpc.ts into FilesService and both callers use it, so the 10 MB
cap, the storage-layer read and the off-thread decode stay in one place. The
RPC keeps its own error wording, which its tests still pin.

/**
* The trip-file MCP surface (FilesMcp): listing a trip's documents, reading one
* document's contents under its own scope, and the attach/describe writes.
*
* The gates are what this file is really about. Every tool has to answer exactly
* what its REST route answers: trip access before anything else, file_edit on
* the writes, and a file id that is only resolvable inside its own trip. And
* read_trip_file has to stay behind files:content while list_trip_files answers
* on files:read alone.
