Implements the "Frontend Theme Redo" design (decision 1a): the logged-in
player portal now uses the same sidebar shell as Admin, and Admin's own
My Characters view gets the same stat-tile treatment.
- PlayerPortalLayout: replace the light 820px top-tab header with the
Admin sidebar shell (icon nav, sticky content header with page title,
signed-in footer with sign out). Reuses .admin-grid so the two
logged-in experiences read as one app.
- Drop the now-redundant inner <h1> from PlayerCharacters/PlayerAccount;
the title lives in the sticky header.
- CharacterStats: new stat-tile row (Characters / Online now / Linked
account) that tolerates a restarting shard and hides until an account
is linked.
- AdminCharacters: render CharacterStats above the roster instead of the
bare intro paragraph, matching the Player Portal Characters page.
