Categorise accounts with colour-coded tags

Feature Request: Tags / Categories for Accounts

Description

Allow users to organise their 2FA accounts by assigning one or more tags to each account. Tags help group related accounts (e.g. "Work", "Finance", "Social") and make it easier to navigate a large vault.

Design Details

• Tag model: a tag has a name and a color chosen from a fixed palette of 10 pre-defined colors
• Palette: provide 10 distinct, accessible colors users can pick from when creating a tag (e.g. red, orange, amber, green, teal, blue, indigo, purple, pink, grey)
• Assignment: users can assign zero or more tags to any account from the account detail/edit screen
• Display: tags are shown as small color-coded chips on the account list item
• Filtering: tapping/clicking a tag chip filters the account list to show only accounts with that tag (works together with type-ahead search)

Storage

• Tags should be persisted in the local vault/database
• Tag data should be included in backup/export so it survives vault migrations

Acceptance Criteria

• CRUD operations for tags (create, rename, recolor, delete)
• Multi-tag assignment per account
• Visual chips shown in account list
• Filter by tag on accounts screen
