Read PENPOT_TENANT env var (defaulting to "default") and embed it in
Redis Pub/Sub channel names as penpot.mcp.<tenant>.task.{req,res}.<id>.
This prevents cross-tenant interference when multiple environments share
a Redis instance, matching the backend convention
(e.g. penpot.rlimit.<tenant>.window.<name> in app.rpc.rlimit).

* ✨ Improve MCP server logging
Log only fingerprints of user tokens
* ✨ Add Loki transport support to MCP server logger
Loki logging is enabled iff PENPOT_LOGGERS_LOKI_URI is non-empty.
File logging is now enabled iff PENPOT_MCP_LOG_DIR is set to a non-empty value
(previously defaulted to the "logs" directory when unset).
GitHub #9415
The ReplServer Express app was calling `app.listen(port)` with no host
argument, causing Node/Express to default to binding on all interfaces
(0.0.0.0). Combined with the unauthenticated /execute endpoint, any
network peer could POST arbitrary JS and get it run inside the MCP
process.
Fix: add a `host` parameter (default "localhost") to the ReplServer
constructor and pass it to `app.listen`. The call site in
PenpotMcpServer now forwards `this.host` (sourced from
PENPOT_MCP_SERVER_HOST env var, default "localhost"), so environment-
variable overrides continue to work.
