Makes `users.email` unique, de-duplicates the addresses an upgrade will find,
and builds the self-service change-and-verify flow that did not exist.
The uniqueness index is on a generated `email_norm AS (LOWER(email)) STORED`
column under `utf8mb4_bin`, NOT on `email` under a `_ci` collation as the plan
specified. Every case-insensitive collation this server offers is also
accent-insensitive: `josé@x.com` and `jose@x.com` compare equal, and those are
two different mailboxes. The plan's index would have refused the second address
forever and the de-duplication would have nulled a legitimate account's.
A requested address is STAGED in `email_pending` and only a tokened link
installs it, so a typo cannot silently redirect account-recovery mail.
`isDuplicateUsername()` now distinguishes the two indexes. All five call sites
branch on it; each answers differently on purpose, because a public form, an
IdP callback, a half-completed invite and an admin screen do not owe the same
person the same amount of truth.
SSO reads the IdP's actual `email_verified`/`verified` claim instead of
inferring verification from an address merely being present.

Self-service account security had three URL surfaces onto one controller. All
three mounted the same `admin/account.controller.js` handlers; each of the three
router files carried a header comment apologising for the arrangement.
`/auth/me/account` was already a strict superset, which settles which to keep:
/admin/account 6 routes noindex, isLoggedIn, staffOnly
/player/account 8 routes noindex, requireAuth
/auth/me/account 10 routes noindex, requireAuth
Neither of the deleted surfaces carried recovery codes, and /admin/account
carried no username or password change at all — so client.js already called
/auth/me/account/recovery-codes/* for two operations on a screen it otherwise
served from /admin/account. The split was leaking before this change.
Gating is equivalent where it overlapped: /player and /auth/me apply identical
`noindex, requireAuth`, and `staffOnly` on /admin/account was strictly narrower
while buying nothing, since every handler is self-scoped to req.user.id. There
is no CSRF layer to differ.
- 14 routes deleted, 0 added, no handler changed.
- account.controller.js moves router/v1/admin/ -> router/v1/auth/, beside the
one router that still reaches it.
- Web client: 14 call sites move onto a root-level api.myAccount /
api.changeUsername / ... group, matching the /auth/me methods already there.
- Android app: no change. MeApi.kt was already 100% /auth/me/account/*.
- Two swagger tags, `Admin · Account` and `Player`, were declared only by the
deleted routes and go with them. The orphaned `AccountStatus` schema goes
too; `PlayerAccount` is re-described as the any-role /auth/me/account shape
(the name is kept so existing $refs resolve).
Breaking to the published OpenAPI surface, accepted deliberately: both consumers
are in this org, and deprecate-then-delete would leave the next phase deciding
whether to add routes to surfaces already marked for removal.
Verification: routes.manifest.json shows exactly 14 deletions and 0 additions.
The OpenAPI spec loses the same 14 paths with zero surviving path definitions
changed; its large textual diff is pure reordering, because removing the
first-mounted router shifts every later path. 1203 server tests, 288 client
tests, 53 bot tests green; check:modules, check:hosts and routes:manifest
--check all pass.
Design of record: docs/website/ENGAGEMENT.md Phase 1a. This lands ahead of
engagement Phase 1b, which adds a self-service email field — written once here
rather than three times.
