fix: add alembic merge migration to resolve multiple heads (#370)

009_wallet_fields and 009_add_archived both descend from
008_encrypt_accounting_pw, causing 'alembic upgrade head' to fail in
deploy.sh with "Multiple head revisions are present". Adds merge migration
010_merge_heads to unify the two branches into a single head.

Also fixes a mypy error in get_owner_endpoint: Starlette 0.36+ requires
TemplateResponse(request, name, context) — request moves out of context dict.
