fix(security): harden model assignment and sensitive data handling

Restrict mass-assignable attributes across user/team/redis models and
switch privileged root/team creation paths to forceFill/forceCreate.

Encrypt legacy ClickHouse admin passwords via migration and cast the
correct ClickHouse password field as encrypted.

Tighten API and runtime exposure by removing sensitive team fields from
responses and sanitizing Git/compose error messages.

Expand security-focused feature coverage for command-injection and mass
assignment protections.
