fix: drop clear-text values and ids from panel dry-run logs

Rebuild logged endpoints from constant path templates and reduce every
payload leaf to a JSON type token, so user/squad UUIDs and PII (email,
telegramId) can never reach the dry-run log as clear text. Resolves
CodeQL py/clear-text-logging-sensitive-data findings.
