feat(tui): improve Events screen hierarchy

[ionfwsrijan]

Summary

Improves the Events screen visual hierarchy and scanability by restructuring the layout to clearly separate:

• the review queue table (left)
• selected event details + identity context (right)
• the operator action bar (right, fixed at bottom)

Adds an Events header notice and stronger section boundaries so verdict/score/identity/endpoint/actions are easier to scan at a glance.

Why

The Events screen already had the right information, but it was visually “flat” and required extra eye effort to distinguish the queue, details/context, and actions. This change aligns the Events screen with the Audit screen’s clearer two-column structure for faster operator scanning.

Scope

• bug fix
• documentation
• tests
• TUI / CLI improvement
• framework integration
• signal change
• configuration or route-policy change

Verification

Commands run:

python -m pytest -q

Notes:

• I ran the relevant tests locally
• I updated docs if behavior changed
• I updated screenshots if the TUI changed materially

Signal-specific notes

Signal type:

• hard signal (trackA)
• soft signal (trackB)
• not applicable

Screenshots

Before:

After:

TUI notes

• before/after screenshots attached
• not applicable

Local-only file check

• I did not accidentally stage local-only files such as adiuvare.yaml or local conftest.py changes
