[Aikido] Fix security issue in fast-uri via minor version upgrade from 3.1.0 to 3.1.2 in apps

[aikido-autofix]

Upgrade fast-uri to fix path traversal and authority spoofing vulnerabilities where improper percent-encoding handling allows policy bypass and host redirection attacks.

✅ 3 CVEs resolved by this upgrade

This PR will resolve the following CVEs:

Issue	Severity	Description
CVE-2026-6321	HIGH	[fast-uri] A vulnerability in URI normalization allows attackers to bypass path-based access controls by using percent-encoded separators and dot segments that normalize to unintended paths. This enables policy bypass attacks where restricted paths can be accessed through specially crafted encoded URLs.
CVE-2026-6322	HIGH	[fast-uri] Normalize function improperly decodes percent-encoded authority delimiters in the host component, re-emitting them as raw delimiters during serialization. This allows attackers to bypass host allowlist checks and redirect requests to unintended authorities.
AIKIDO-2026-10784	HIGH	[fast-uri] A path normalization vulnerability allows attackers to bypass security checks by using percent-encoded slashes and dots that are decoded before dot-segment removal, causing distinct URIs to normalize identically and compare equal.
