feat(ai-agents): missions lookup + simple policy + agent fingerprint (UX 3-6)

Four UX improvements that make agents more discoverable and their
behavior more transparent. All svelte-check clean (0 errors in
changed files).

=== UX 3: Reverse-Mission-Lookup ===

Agent detail view now shows a "Missions (N)" section listing all
missions owned by this agent with status dots + state labels. Includes
a "+ Neue Mission für [agent]" button that navigates to the template
gallery. Users no longer have to mentally cross-reference between the
agents and missions modules.

=== UX 4: Simple-Mode Policy ===

The Policy section defaults to three radio-card presets:
- Standard (Vorschlag für alles)
- Vorsichtig (alles Vorschlag, keine Auto-Writes)
- Aggressiv (gleichartige Schreibvorgänge automatisch)

The full per-module matrix is now hidden behind "▸ Erweitert
anzeigen". This covers 90% of users who just want a quick
conservative/aggressive toggle. Power-users still get the full
matrix.

=== UX 5: Policy Natural Language Summary ===

Above the preset radios, a preformatted block summarizes the current
policy in plain German: "Gesperrt: X, Y · calendar: automatisch ·
Alles andere: Vorschlag". Generated from the policy object. Updates
live when the user switches presets or changes module overrides.

=== UX 6: Agent Fingerprint on List-Views ===

New <AgentDot record={item} /> component: reads __lastActor from
any Dexie record, resolves the agent's avatar via the live useAgents
query, and renders a tiny inline emoji dot next to the item title.
When no AI actor wrote the record, renders nothing (zero-width).

Wired into:
- /todo — task title row, after the title span
- /notes — note title row, after the title span

Each module import is a single line (`import AgentDot from ...`);
the component is self-contained (owns its own query + styles).

+  AgentDot — tiny inline indicator showing which AI agent last wrote

+  when kind='ai', resolves the agent's avatar from the live agent

+  Usage:
+    <AgentDot record={task} />
+    <AgentDot record={note} />

+  Intentionally minimal: one emoji dot + tooltip. No click handler

+  is inline with zero width when hidden.
