#4005 feat(settings): profile menu, danger zones and DaisyUI buttons

Summary

• Profile menu: clicking the user name opens a popover with Account settings and Log out. Sign out is removed from the account settings page on the web; the native app keeps it there because it has no sidebar.
• Settings entry: the main sidebar gets a Settings item that opens the current organization's settings (still tab based).
• Buttons: settings buttons use the DaisyUI classes from the AGENTS.md rule (d-btn-primary for Save, d-btn-outline for secondary actions, d-btn-error for deletes). Save buttons read Save, are left aligned and have no separator on account, change password, organization and app settings.
• Danger zones: delete account, delete organization and delete app move into a Danger zone card that says why it is dangerous and what each action removes. App settings draw their own card so the danger zone sits below it.

Screenshots (left: before, right: after)

The settings pages keep their existing tabs; dedicated settings sidebars were dropped from this PR. Screenshots below predate that change and still show the settings sidebar.
