fix(pulse): Finances tab reads 0 income/expenses off LifeOS's own shipped templates

[takanorinishida]

Two independent bugs in /api/life/finances, both hit by installs that follow the shipped USER/TELOS/FINANCES templates as-is (not specific to any one deployment's data):

• parseCurrencyTable() always read the amount from column 1. LifeOS's own EXPENSES.md ships as | Category | Vendor | Amount | Frequency | Notes | — column 1 is Vendor (never numeric), column 2 is Amount. Every install using the shipped layout silently got 0 for every expense row.
• INCOME.md ships as bulleted prose with no pipe-table at all (the code comment claiming it "leads with 'Annual Income Estimate'" doesn't match the shipped file), so parseCurrencyTable(incomeRaw) always returned [] and every install's income read as $0/¥0 — which then propagates into the Sankey, the 12-month trend, and the post-tax net.

Fix

• parseCurrencyTable() now picks the amount column by header name ("amount", "annual", "monthly", "total", "cost", "value"), falling back to column 1 when no header matches so tables that already worked are unaffected. When a Frequency/Cadence/Period column is present, its value now annualizes a per-period amount via the existing cadenceToMonthly() instead of taking the cell at face value.
• Per-source income bullets use inconsistent ad hoc keys ("Gross per period", "Current MRR", "Per-engagement amount", ...), too heterogeneous to sum reliably, so this doesn't attempt that. Instead a new parseCurrencyBullet() reads the one number both the shipped template and hand-written files anchor on — the "## Expected Monthly Total" section's headline bullet — only as a fallback when the table is empty.

Non-destructive

Both changes only add coverage for inputs that previously parsed to 0/[] — nothing that already extracted a nonzero number changes.

Verification

Ran both parsers against the shipped USER/TELOS/FINANCES/{INCOME,EXPENSES}.md templates (still correctly yield nothing — placeholder $X,XXX text has no digits) and against a filled-in real install: income moved from ¥0 to the correct ¥4,800,000/year, expenses correctly read ¥1,524,000/year off the Amount column instead of the Vendor column.
