fix(member-profile): hoist parsed URL variable outside try block

[bokelley]

Closes #4257

The member profile edit page threw ReferenceError: parsed is not defined on every page load for org members who already have a photo URL saved. The parsed variable was declared with const inside the try {} block (block-scoped, not visible outside), then referenced after the block at img.src = parsed.href. Hoisting to let parsed; before the try resolves the scope error.

Non-breaking justification: This is a single-variable scope declaration change in client-side UI JavaScript. No API, schema, or protocol surface is touched. Existing orgs without a photo URL are unaffected; orgs with a photo URL now load the page correctly instead of crashing.

Pre-PR review:

• code-reviewer: approved — fix is mechanically correct, no uninitialized-access risk (both early-return paths in catch/protocol-check fire before parsed.href is reached), no security concerns
• internal-tools-strategist: approved — fully addresses the reported issue, low regression risk, no other code paths affected
