Per-account product-name branding

Account admins can now replace "WaboSign" in the UI, emails, audit-trail
PDFs, and authenticator-app issuer with their own product name. The
brand override is stored as an AccountConfig row (brand_name key),
managed from /settings/personalization above the logo upload.

Resolution flows through Wabosign.branded_product_name(account = nil):
  1. account&.brand_name if a record is passed
  2. else the deployment's oldest non-archived account's brand_name
     (so anonymous surfaces like the landing page, PWA manifest, and
     og:title get the operator's brand on single-tenant installs)
  3. else Wabosign::PRODUCT_NAME ("WaboSign")

AGPL §7(b) DocuSeal attribution stays untouched:
  - _powered_by.html.erb second line keeps Wabosign::UPSTREAM_NAME
  - _email_attribution.html.erb second paragraph keeps it
  - completed.vue keeps its hardcoded DocuSeal link
The Wabosign::UPSTREAM_NAME and UPSTREAM_URL constants stay constants —
they are never overridable.

Swapped 41 direct Wabosign.product_name callers to pass the most-local
account in scope (current_account, @template.account,
@submitter.submission.account, submission.account, or nil for chrome
without account context). Mailers' default `from:` is now a lambda that
reads @current_account per message. SIGN_REASON constant in
generate_result_attachments became sign_reason_template(account) so
PDF signature reasons reflect the brand.

The two i18n keys actually rendered with literal "WaboSign"
(welcome_to_wabosign in templates_dashboard, connect_to_wabosign_mcp
in mcp_settings) are parameterized to %{product_name} across the 7
locales that defined them. The other ~9 WaboSign-branded i18n keys
are unreferenced dead code from the Pro paywall and stay as-is.

Specs:
  spec/models/account_spec.rb (new) — Account#brand_name
  spec/lib/wabosign_spec.rb (new) — branded_product_name precedence
  spec/requests/personalization_settings_spec.rb (new) — end-to-end
