Fix profile links to bypass redirects

[jmgasper]

Summary

• Send member-handle links directly to the environment-specific Profiles app.
• Normalize header menu and account links produced by the legacy navigation dependencies.
• Update snapshots, URL helper coverage, and browser smoke-test expectations.

Root cause

Community App still generated /members/:handle links and depended on the legacy Topcoder redirect. When that redirect failed, profile navigation failed with it.

Impact

Profile clicks now go directly to profiles.topcoder.com/:handle in production and profiles.topcoder-dev.com/:handle in non-production environments. Existing API requests and legacy badge/detail routes remain unchanged.

Validation

• Full Jest suite under the repository's Node 10 runtime: 154 suites passed, 347 tests passed, 141 snapshots passed.
• ESLint passed for all changed application JavaScript/JSX files.
• JSON validation passed for the updated smoke-test environment configs.
• Verified the commit merges without conflicts and produces the same focused diff against both develop and master.
• Smoke-test TypeScript compile was not run because that subproject's dependencies are not installed locally.
