271-295: Normalize and bound pasted observer keys before appending.

Line 290 appends arbitrary filtered text with no hex/length guard. Since this field represents a 64-char hex key, enforce that at paste time to prevent hidden invalid growth.

In `@src/ui/key_handler/mod.rs` around lines 271 - 295, The observer paste
handling currently appends arbitrary filtered text to
app.observer_shared_key_input; change it to normalize and bound pasted content
to a 64-char hex key: after obtaining text from
read_clipboard_text_best_effort() and stripping control chars, trim whitespace,
strip any leading "0x"/"0X", retain only hex characters [0-9a-fA-F], convert to
lowercase (or a consistent case), then compute remaining =
64usize.saturating_sub(app.observer_shared_key_input.len()) and append only up
to remaining characters of the cleaned hex string to
app.observer_shared_key_input; only append if at least one character is added
and return Some(true) as before (affects symbols: app.observer_shared_key_input,
read_clipboard_text_best_effort, AdminTab::Observer, Tab::Admin).
