feat(pii): Wire Rails log-subscriber data (active_record, mailer, active_job)

[sl0thentr0py]

Stack position: 7/10. Blocked by #3001**,** #3002**.**

Gate the remaining Rails log-subscriber attributes via data_collection.

Gate sites (sentry-rails)

• lib/sentry/rails/log_subscribers/active_record_subscriber.rb:52-59: SQL bind params → database.query_params
• lib/sentry/rails/log_subscribers/action_mailer_subscriber.rb:44-46 (message_id) and :76-79 (params, filtered)
• lib/sentry/rails/log_subscribers/active_job_subscriber.rb:50-53: job arguments (filtered)

Files & tests

• the three subscribers + parameter_filter.rb (reuse)
• spec/sentry/rails/log_subscribers/active_record_subscriber_spec.rb, action_mailer_subscriber_spec.rb, active_job_subscriber_spec.rb, log_subscriber_spec.rb

Security-sensitive: DB bind values, mailer params, job args.
