[V2][team] Vendor Mail Tracker - Security and performance hardening

[kryputh]

Goal

Add safety and performance constraints for this tool before any future integration.

Tool: Vendor Mail Tracker

Release tier: V2

Audience: team

Required labels

This issue must carry these campaign labels:

• GrantFox OSS
• Maybe Rewarded
• Official Campaign
• Tooling Ecosystem
• V2 Later Tool
• Team Tool

Implementation folder

All work for this issue must stay inside:

text tools\v2\team\vendor-mail-tracker/

V2 later-release tool. Build the tool as complete isolated work, but do not link it to the main app yet.

Do not modify the main application shell, dashboard layout, navigation system, authentication, wallet core, mail rendering engine, existing inbox architecture, existing routing, Stellar integration core, database schema, or existing design system.

Deliverables

• Document threat assumptions and unsafe inputs for the tool.
• Add validation, sanitization, or guard helpers where relevant.
• Add performance notes for large emails, attachments, teams, or histories.

Acceptance criteria

• The tool has explicit handling for malformed or hostile input.
• The tool avoids unnecessary work on large datasets.
• No existing security-sensitive app code is modified.
• Files changed by this issue are limited to $rel/.
• The contribution is reviewable as a self-contained mini-product change.

OSS contributor notes

Keep the work small and reviewable. Prefer local fixtures, local docs, local tests, and folder-local components/services/hooks. If the tool needs a future connection to the main mail app, write that as a follow-up issue instead of adding the integration here.
