Issue 116: Implement repository reuse logic for deployment updates

[temma02]

Description
Ensure deployment updates reuse the correct GitHub repository instead of provisioning a new one.

Requirements and context

• Must be secure, tested, and documented where applicable
• Should stay reviewable and fit the current monorepo structure

Suggested execution

• Create branch: issue-116-implement-repository-reuse-logic-for-deployment
• Keep changes scoped to the issue and reference the task IDs in the PR

Implement changes

• Look up the existing repository binding from the deployment record
• Guard against reuse when identity data is incomplete or invalid
• Return clear remediation errors when reuse is impossible

Test and commit

• Run the most relevant tests for the touched service or UI surface
• Include screenshots or request/response examples when the change is user-facing
• Call out edge cases, assumptions, and any follow-up work

Example commit message
feat: add repository reuse logic

Guidelines

• Prefer small, reviewable PRs
• Keep naming and data contracts consistent with the spec docs
• Preserve responsive and accessible behavior for frontend work
