fix: tenant-config fixes, cashier/share/savings UI bugs, and menu-access hardcoding

- Add Balance Sheet report and disabled-features accounting config
- Point menu-access tenant header and env.js/environment.ts tenant identifier
  at env config instead of hardcoded 'default'/'lincpay' literals
- Surface the real backend error (not a generic "no reference id") when an
  OTP send fails in contact-otp-block
- Fix branch-day "₹null" display bug (null vs undefined) and add a guard
  blocking a branch's first-ever day open before cash denomination migration
- Dynamically size the denomination count input and block re-opening an
  already-open business day from Migrate Cash Denomination
- Lock the denomination-managed cash GL row in Migrate Opening Balances
  (read-only, with a link back to Migrate Cash Denomination)
- Remove duplicate Cancel/Submit action bars on the Share Product and
  Savings Account creation preview steps; align Previous into the same row
- Hide "Apply Collection" on a share account once its advance collection
  is already settled (further purchases go through Apply Additional Shares)
