Accounting: A/P-clearing payments, check return address + MICR gaps, dashboard fixes

Bill/vendor payments:
- Bill "Pay" and bank-register vendor debits now clear Accounts Payable
  (Dr A/P / Cr Bank) instead of re-debiting the expense, which had
  double-counted expenses in the P&L and never cleared A/P. The expense
  account is kept as a display-only category on the payment.

Checks:
- Bill-payment checks now print the return address (payer name/address)
  from the company check layout (was hardcoded blank).
- Per-segment MICR gap control (check# / routing / account) in both check
  generators, wired to Check Setup (bill payments) and the Check Layout
  editor (Print Checks). New columns: check_settings.micr_gap_1/2 and
  check_layouts/company_check_layouts.micr_gap_1/2.

Accounting Dashboard / Financial Overview:
- Date-range selector (presets + custom) drives the charts, top expenses,
  and recent transactions.
- PDF title renamed to "Financial Overview" and shows the period.
- Fixed amounts rendering as "$ 5 0 0. 0 0": the U+2212 minus sign forced
  jsPDF into a UTF-16 fallback; replaced with an ASCII hyphen (also in the
  report PDF out-of-balance line).

DB migrations applied to the project: repost_gl_on_line_item_change,
budget_actuals_accrual_owner_income, add_micr_gap_controls.
