Upload a file for an attachment field, as the builder

The builder plane's half of files.upload.

POST/v1/apps/{appId}/tables/{tableId}/files

Takes the BYTES as multipart/form-data under file, with recordId saying which record they will belong to, and answers with the descriptor to write into an attachment field. Attaching it is an ordinary record write, so the file arrives through the same op log and the same undo as any other value.

Requires the records:write scope. Operation apps.files.upload. Not an MCP tool: a file is bytes and a tool call is JSON; upload with REST or the CLI. CLI, once published: gtable apps files upload.
