Add notifications column to first deck

[dsaxton]

Default deck for a new user looks like this after the change:

I did notice this panic / crash though if I try to click the "add new column" button:

thread 'main' panicked at crates/notedeck_columns/src/app.rs:600:23:
Added more `Strip` cells than were pre-allocated (3 pre-allocated)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I get the same on master though so I don't think it's related.

Relates to #599

looks like there's a bug where columns added this way:

2025-03-10T18:52:48.116051Z ERROR notedeck_columns::ui::timeline: tried to render timeline in column, but timeline was missing

I've noticed this sometimes in other context and was introduced in my Timeline refactor:

fd030f5

I'll use this branch as a failing test case

I was noticing those errors too, although just now (after reordering the columns in the default deck for better looks / UX) it crashed without ever hitting those empty timeline errors:
