fix(freehire-search): keep the salary period so a yearly figure isn't read as monthly (#504)

formatSalary printed only the currency and amounts, although freehire's
enrichment records the pay period. `detail software-developer-trainee-codifi-fra635ux`
printed `INR 300000–300000` while the API returns `salary_period: "year"`
for that posting, so a yearly salary screened against a monthly figure
read as twelve times its real monthly value.

Append the period when freehire records one (`INR 300000–300000/year`,
`INR 12000/month`); a record without a period prints exactly as before.
Two new parsing.test.ts cases pin it; both fail on the old formatter.
