## Summary
- Allow setting the **current market value** (balance) when creating a
real estate account — the balance field existed for other account types
but was hidden for real estate
- Add an **annual revaluation percentage** field to real estate
accounts, editable from both the creation form and the property details
card on the account show page
- Create a scheduled command (`real-estate:apply-revaluation`) that runs
monthly on the 1st to automatically adjust property values by
`revaluation_percentage / 12 / 100`
## Details
### Backend
- Migration adds `decimal('revaluation_percentage', 5, 2)` nullable
column to `real_estate_details`
- Validation: nullable numeric, range -100 to +100 (negative for
depreciation)
- `ApplyRealEstateRevaluationCommand` finds all accounts with a
non-null/non-zero percentage, gets the latest balance, and upserts the
new balance for today
- Scheduled `->monthlyOn(1, '00:00')` in `routes/console.php`
### Frontend
- Added `real_estate` to `BALANCE_ACCOUNT_TYPES` so the Market Value
field appears during creation
- Added Annual Revaluation (%) input to both the creation form and the
property details card
- Read-mode displays formatted percentage with sign (e.g.,
"+3.50%/year")
### Tests
- 6 new tests in `RealEstateTest.php` covering creation with balance,
revaluation %, negative %, validation, PATCH update, and clearing to
null
- 8 tests in `ApplyRealEstateRevaluationTest.php` covering
positive/negative revaluation, skip conditions, latest balance usage,
multiple accounts, and upsert behavior
