@W-21332566 - Use getConnection instead of axios

[ad-shreya]

What does this PR do?

Uses getOrgService instead of axios.
Benefits of using getOrgService-

• getOrgService().getConnection(username) uses the Salesforce CLI’s stored auth (e.g. from sf login). You don’t manage access or refresh tokens yourself.
• getConnection() only returns a connection for orgs that are in the MCP allowlist (allowedOrgs). Unlisted orgs are rejected with a clear error.
• All tools use the same pattern: getOrgService().getConnection(usernameOrAlias) then call connection.

Is this still used?

mcp/packages/mcp-provider-devops/src/commitWorkItem.ts

Line 64 in 7adefb7

if (gitFolder === deployFolder && gitFile === deployFile) {

I am seeing some old connection logic

Looks like axios is still in your package.json can you remove it and rebuild your yarn.lock?

I am still seeing a few places that are using import { getConnection } from "./shared/auth.js" instead of getting the connection off of the services. Is there a reason for these?
