Sprint 3.1: War frontend completion — Intelligence Panel, Alliance Wars section, Scan Enemy

[Copilot]

Completes the remaining B-1 gaps in the war frontend: War-Intelligence-Panel, visible Alliance Wars, and War-Goal-Score display. All war mechanics are now fully controllable from the UI.

Backend (api/war.php)

Two new GET endpoints:

• get_intel&war_id=X — queries enemy fleet count, colony count, alliance affiliation, and resource scan (65% accuracy factor) for any war the player participates in
• alliance_wars — resolves the player's current alliance from alliance_members and returns all active alliance_relations rows with relation_type='war'

API client (js/network/api.js)

• warIntel(warId) → get_intel (30s TTL cache)
• warAllianceList() → alliance_wars (10s TTL cache)

War UI (RuntimeWarController.js)

• allianceWarsHtml(myAlliance, allianceWars) — renders an Alliance Wars section in the war overview showing [TAG] Name, target, and declared date; shown in both empty and populated list states
• intelPanelHtml(intel) — stat cards for enemy fleets, colonies, alliance, and estimated resources
• 🔍 Scan Enemy button added to active-war detail header; injects intelPanelHtml into a [data-intel-host] placeholder on click
• WarController.render() now loads war list + alliance wars via Promise.all

// Detail view header (active war only)
<button data-intel-load="${warId}">🔍 Scan Enemy</button>
// → async fetches api.warIntel(warId) → renders fleet/colony/resource stats inline

Tests (tests/js/war-events.test.js)

Expanded from 20 → 31 tests: 7 for Alliance Wars section (loading, rendering, empty/null states, user targets) and 4 for the Scan Enemy button and intel panel rendering.
