feat: signed-in state uses the shared OTM account menu (0.6.2)

Replace the ad-hoc "sign out" link next to the AI names toggle with
@otm/account-panel's OtmAccountMenu (avatar, OTM badge, Manage OTM
account, Sign out), and fold the "Sign in with OTM" helper line into
AiControls using the module's OTM_HELPER_LINE constant instead of a
hardcoded duplicate in Finder.tsx. Bumps @otm/account-panel 0.32.0 →
0.44.0 (already wired via .npmrc + transpilePackages for the
suggestions widget).
