* fix(family-sharing): prevent silent data loss when rehoming or removing users

Fixes #1689.

Two destructive paths could strand a pre-existing user's family and accounts:

1. Invitation#accept_for unconditionally overwrote user.family_id, orphaning
   the prior family + its accounts with no user able to reach them.
2. Settings::ProfilesController#destroy then called @user.destroy when an admin
   removed the rehomed member, destroying the only login path back to the
   now-orphaned data.

Add hard-block guards on both paths. accept_for refuses when the invitee
already belongs to a family with accounts; ProfilesController#destroy refuses
when the member owns accounts in another family (legacy state from the old
flow). InvitationsController#create surfaces a specific, actionable flash so
the admin understands why the auto-accept was refused.

No automatic recovery of already-orphaned data — that needs a separate
one-shot script per dosubot's analysis on the issue.

* fix(family-sharing): scope invite orphan-guard to invitee-owned accounts (#1896 review)

Codex flagged (P1) and the maintainer review independently raised that
would_orphan_existing_family? keyed off user.family.accounts.exists? —
any account in the invitee's current family — which wrongly blocked a
non-owner member from leaving a multi-user household.

Rename to would_orphan_owned_accounts? and key off
user.owned_accounts.where.not(family_id: family_id), making the invite
guard symmetric with the destroy-path guard in
Settings::ProfilesController. A member who owns no accounts now orphans
nothing by moving and is free to accept the invitation; an owner is
still blocked.

Add a regression test for the non-owner case and update the existing
tests to give the invitee explicit account ownership.

* Remove extra comments per project conventions
