Add platform adapters: Intigriti, YesWeHack, Immunefi

[tikket1]

Feature Request

Expand ScopeVault beyond HackerOne to support additional bug bounty platforms with researcher-facing APIs.

Platforms to integrate

Platform	API Type	Priority	Notes
Intigriti	REST API	High	Growing EU base, excellent triage speed
YesWeHack	REST API	Medium	EU-focused, API-based platform with full integration support
Immunefi	REST API (read-only)	Low	Web3/DeFi, can list programs and scope but no report management

Excluded platforms (no researcher-facing API)

• Bugcrowd -- API is customer-only; AI Connect is for customers piping data to AI/ML, not researcher access
• Synack -- Enterprise API only, no official researcher API (community lib uses undocumented endpoints)
• Cobalt -- API is customer-facing for managing pentests, no researcher portal API
• HackenProof -- No documented API for researchers

Implementation approach

Each platform needs an adapter implementing the existing BaseAdapter interface:

• fetch_programs() - list programs
• fetch_program_detail() - program details
• fetch_scope() - scope assets for a program
• fetch_reports() - user's reports (where supported)
• fetch_report_detail() - report detail with activities (where supported)

Architecture

The adapter pattern is already in place (apps/api/scopevault/adapters/). Each new platform needs:

1. A new adapter file (e.g., intigriti.py)
2. Auth configuration in settings (API keys/tokens per platform)
3. Response mapping to the existing ProgramData, ScopeAssetData, ReportData models
4. Platform-specific rate limiting configuration

Settings UI

• Onboarding wizard should support multi-platform setup
• Settings page needs per-platform credential management
