Bug: Replies to blocked (?) messages are not indented properly. OR, blocked messages need a placeholder for clarity.

Environment:

• OS: iPadOS 17.5.1
• IceCubesApp version: 1.10.44

Description

When rendering a response to a message that isn't available (because the user is banned or the message is blocked? I'm not sure), indentation starts again at the left edge, as if it was another "root" message.

Using the thread at https://zirk.us/@JamesGleick/112745157496900493 viewed from a mastodon.social account as example:

Here's the context of the root post. Everything looks fine here:

Here, Tom Ritchford appears to be replying to nobody. Upon closer inspection, seems like there's a post from HarbingerOfSalem that we can't see. But note that Ritchford's post has no indentation:

(Navigating to HarbingerOfSalem's profile does show content, so the user is not blocked.)

Here, RodneyPetersonTalentAgency also appears to be responding to nothing:

And indeed pJotoro's account shows no posts nor replies:

Suggest creating a placeholder for the missing message (ideally with the reason, e.g., "[blocked]") and indenting any replies to the missing message to avoid confusion.

Reproduce the thread at the linked Mastodon URL in IceCubesApp 1.10.44 on iPadOS, focusing on replies whose parent message is unavailable. Trace the thread-rendering entry point to determine how missing parents affect indentation. Done means missing messages have a clear placeholder or equivalent context and replies retain their correct indentation.
