🔒 GDPR Vue — Download-my-data button + repoint Delete-Account to /me/data

[PierreBrisorgueil]

Front-end for the two data-subject rights.

Scope — src/modules/users/views/user.profile.view.vue

• Add a "Download my data" button (mirror the inline-axios profile pattern) calling GET /users/me/data → client-side JSON blob download.
• Repoint deleteAccount axios.delete from /users to DELETE /users/me/data (the cascade endpoint) so erasure actually fires the provider registry, + add a re-auth confirm to the delete dialog.
• Optional: add export/erasure-rights copy to the legal privacy template.

DoD

• /verify + build green.
• Visual smoke of both buttons against the running API (runtime-verify the real contract shape, not a self-authored mock).

Depends on: GDPR export+erasure controller (the backend contract).
