fix(ui): resolve 5 medium UI issues (Home, Hub, Login, Borrow, Transfer)

Overview

Address five Medium UI bugs across Home, Hub, Login, Borrow, and Transfer to card. Four behavior fixes are verified. The misleading Transfer-to-card picker has been withdrawn until a per-card backend routing contract exists.

1. Home — Balance visibility eye affects the entire screen

• Lark: https://hola-tech.sg.larksuite.com/record/MmmjrLFHPehH7Ocnb8MlZHSbgng
• Module / Screen: Home
• Priority: Medium
• Actual: Tapping the eye toggles both the upper balance and the amounts below; hiding the upper balance also hides every amount on the screen. https://screenrec.com/share/FecyO1m6lM
• Expected: The eye only toggles the upper balance and does not affect the amounts below. https://prnt.sc/A3OuzBaArRkh
• Fix: Stop passing isBalanceHidden to Assets; the eye now controls only the upper balance in HomeHeader.

2. Hub — Software keyboard covers the calendar

• Lark: https://hola-tech.sg.larksuite.com/record/UQXJrHCz5eRlVDcAfkHlNndPgZ0
• Module / Screen: Hub
• Priority: Medium
• Actual: With the software keyboard open, tapping a date field opens the calendar underneath the keyboard. https://screenrec.com/share/6d7N8Vri0s
• Expected: Tapping a date field dismisses the software keyboard and displays only the calendar.
• Fix: DatePickerModal.present() dismisses the software keyboard centrally before presenting the calendar; redundant caller-side dismissals were removed.

3. Login — Black and empty screens flash during initial loading

• Lark: https://hola-tech.sg.larksuite.com/record/Josfr8JjMejIgEctZM4lXFJtgLc
• Module / Screen: Login
• Priority: Medium
• Actual: After login, the app shows a black screen, then an empty screen, before flashing and rendering the correct data. https://screenrec.com/share/wDP0NkuUGO
• Expected: Render the correct loading and data states from the start.
• Fix: Render a themed loading indicator instead of null during auth/profile bootstrap, use router.replace('/') after login, and add an explicit loading state to Assets to prevent an empty-state flash.

4. Borrow — Duplicate debt values

• Lark: https://hola-tech.sg.larksuite.com/record/XQEnroZRaeZOdlcc2KBlUI4tg3b
• Module / Screen: Borrow
• Priority: Medium
• Actual: The same debt value is displayed more than once. https://prnt.sc/a4LdlE2lXGRI
• Expected: Display the value only once to avoid ambiguity.
• Fix: Keep one exact debt value in the hero using formatAmount; remove the duplicate Borrowed row and do not replace it with a rounded-only display.

5. Transfer to card — Destination card cannot be selected

• Lark: https://hola-tech.sg.larksuite.com/record/AzSyrhDaSebEFbc0JMjlBMu9gzb
• Module / Screen: Transfer to card
• Priority: Medium
• Actual: With two cards available, the transfer automatically selects one card without letting the user choose. https://prnt.sc/TfkjAuSNbedf
• Expected: Display the available cards and let the user choose the destination card.
• Review remediation: Removed CardSelectSheet, cardId routing props, and all picker-only tests. The form retains the generic card-account destination and no longer claims that a selected card receives the funds.
• Open dependency: A complete Bug 5 fix requires a backend/provider contract that routes deposits by cardId; the current API routes only by cardAccountId/cardholderNo.

Verification

• pnpm lint: 0 errors.
• pnpm type-check: pass.
• Targeted Jest: 109/109 tests pass across 9 suites.
• Maestro E2E passes the four behavior fixes and a guard proving the misleading picker is absent. Per-card deposit routing remains outside the flow.
