* Fix NoMethodError when entry has nil entryable
Guard against orphaned entries where the entryable record has been
deleted but the entry still exists, preventing a crash on the
account show page.

* Add dependent: :destroy to Entryable has_one :entry
The polymorphic has_one :entry association lacked a dependent option,
meaning if a Transaction/Trade/Valuation was ever deleted directly
(bypassing the Entry), the Entry would be left orphaned with a nil
entryable — causing NoMethodError in the activity feed.

* Add nil entryable guard to _split_group.html.erb
Same defensive check as _entry.html.erb for consistency.
