feat(eba): consolidate event bindings, fix command.tsx pointer-events

- Replace legacy pipeline binding card + RoutingRulesEditor with unified
  EventBindingsEditor; remove use_pipeline_uuid/pipeline_routing_rules
  from bot form schema and API update handler
- Add _augment_event_data() to botmgr for filter virtual fields
  (message_text, message_element_types, chat_type)
- Add alembic migration 0009: migrate use_pipeline_uuid and
  pipeline_routing_rules into event_bindings on first run
- Fix command.tsx: data-[disabled] -> data-[disabled=true] so cmdk 1.x
  items (data-disabled=false) are not pointer-events:none
- EventBindingsEditor: onSelect on CommandItems, filter conditions panel,
  disabled bindings section, dnd reorder
- i18n: add filter/condition keys for zh-Hans and en-US
- Update tests to match new bot service behavior
