New: Web Setup Wizard

First-launch web setup wizard. New installs no longer need to hand-edit .env.local - point a browser at the container and the wizard probes the JMAP server(s), configures OAuth/OIDC, generates the session secret, accepts branding uploads, and provisions the initial admin password. Admin storage is now split into ADMIN_CONFIG_DIR (operator-authored, mountable read-only after setup) and ADMIN_STATE_DIR (runtime audit log and login timestamps); the legacy ADMIN_DATA_DIR keeps working for existing installs.

Features

• Setup: Web setup wizard with multi-step flow: Server, Auth, Security, Logging, Branding, Review, Admin
• Setup: Admin config/state directory split with optional ADMIN_CONFIG_READONLY for immutable deployments (#226)
• Setup: File uploads on the wizard branding step
• Setup: Redesigned review step with grouped summary and an advanced toggle for the full config
• Setup: Require explicit confirmation when JMAP probe finds no session
• Mail: Drag attachments out of the viewer to the local file system (#267)
• Mail: Reading Pane at Bottom mail layout (#262)
• Mail: Configurable signature position – above or below quoted text (#266)
• Mail: Signature position is now searchable from the email behavior settings
• Mail: Show avatar in Focused list for compact density and above
• Mail: Align Focused list preview with other layout previews
• Compose: From-header override in the composer with catch-all auto-reply, replies to an alias on a domain you own pre-fill the alias as the sender even when it isn't a configured identity (#246)

Performance

• Mail: Prefetch initial email data on login
• Auth: Parallelize login round-trips and drop redundant JMAP re-verify

Fixes

• Auth: Skip upstream JMAP reverify for trusted URLs (#237)
• Auth: Show account identity in the switcher header instead of the sending alias
• Compose: Fall back to the primary identity signature on reply
• Setup: Drop redundant first-login banner about removing ADMIN_PASSWORD (#222)
• UI: Consistent notice cards for server probe results
