v4.0.5

Component architecture
- Reorganise src/lib/components into pages/, sections/, ui/ subdirectories and
  update all imports across routes and tests.

Owner admin dashboard (+2k lines)
- Scheduled welcome-pack emails: durable queue with cancel/reschedule and a
  background sender loop (SCHEDULED_CHECK_INTERVAL_SECONDS, default 60s).
- Custom welcome-pack subject line, preview recipients, and client BCC.
- Add-client, edit client profile, and reset-onboarding flows.
- "View as client" onboarding preview (owner impersonation, dry-run submit).
- Tabbed owner welcome route (/owner/welcome/[[tab]]).

MYOB integration
- New mail_api/myob.py: create new clients as MYOB AccountRight customer
  contacts. Disabled until all MYOB_* env vars are set (no-op otherwise).

Onboarding
- New "Does your dog resource guard?" Yes/No question in the Behaviour step.
- Persist vetAddress, flea/tick, and pet-insurance fields server-side.

Misc
- vite config, new hooks.ts, responsive CSS tweaks, deploy/docker config,
  mail-api README and start-dev.ps1.
