## What
Adds an **Edit** button (icon-only, top-right) to the dashboard accounts
grid, next to a new **Accounts** section title. It opens a dialog for
managing accounts:
```
Accounts [edit]
[ acc 1 ] [ acc 2 ]
[ ] [ ]
```
Each dialog row shows:
- the bank logo + account name
- an **eye toggle** (open/closed) to hide or show the account on the
dashboard grid
- a **drag handle** to reorder
## Behavior
- **Visibility**: hidden accounts disappear from the grid but stay in
the net worth chart/totals and remain in the dialog so they can be
re-enabled. Backed by a new `hidden_on_dashboard` column.
- **Reorder**: moved entirely into the dialog (over *all* accounts,
including hidden) instead of dragging the cards. This keeps a single
source of truth for `position` — dragging visible-only cards would have
left hidden accounts' positions inconsistent. The card-level drag handle
was removed.
- Both actions use optimistic UI, mirroring the existing reorder flow.
## Changes
- Migration: `hidden_on_dashboard` boolean on `accounts` (hidden from
default serialization like `position`, surfaced explicitly in the net
worth evolution payload).
- `AccountController::updateVisibility` +
`UpdateAccountVisibilityRequest` (owner-authorized) and the
`accounts.visibility` route.
- New `AccountsManagerDialog` component; dashboard header + plain grid;
removed the now-unused `dragHandle` prop from `AccountBalanceCard`.
- New `es.json` keys.
## Tests
Added feature tests for the visibility endpoint (toggle, validation,
ownership). Full `AccountControllerTest` and `DashboardAnalyticsTest`
suites pass; lint and types are clean on the touched files.
