Replace display:none (hidden class) with visibility:hidden/visible for all
error, warning, and status message elements across the extension UI. This
prevents layout shift when messages appear or disappear.
Changes:
- helpers.js: showError/hideError now use visibility instead of hidden class
- index.html: all error/status divs use visibility:hidden + min-height
- confirmTx.js: warnings, errors, fee section use visibility
- approval.js: tx-error, sign-error, danger-warning use visibility
- addressDetail.js: export-privkey-flash uses visibility
- deleteWallet.js: delete-wallet-flash uses visibility
- addWallet.js: phrase-warning uses visibility
- receive.js: erc20-warning uses visibility
- addToken.js: add-token-info uses visibility
- settingsAddToken.js: settings-addtoken-info uses visibility
Replace the inline confirmation div at the bottom of Settings with a
proper full-screen view (view-delete-wallet-confirm). This fixes the
issue where the confirmation was offscreen on the 360x600 popup.
- New view with back button, title, warning text, password input,
and red-text Confirm Delete button
- Dedicated flash area for password errors
- New deleteWallet.js module with init/show pattern
- Added delete-wallet-confirm to VIEWS array in helpers.js
- Removed old inline confirmation HTML and logic from settings
