Sol Stake: Discover and show Solana staking accounts

[jirih-stsh]

User Story

As a Solana user I want to see all the staking accounts attached to my Solana account, So that I can see how much SOL I have staked across all delegators

Requirements

• do discovery - discover all staking accounts under the users Solana account
  • we want to discover both accounts delegated to Everstake, but also to other validators
• add Staking tab in Solana account
  • show a table with a list of all discovered staking accounts (see the design file bellow)
  • for each of the discovered staking accounts we should show a separated staked amount
  • we should visually differentiate which staking accounts are delegated to Everstake
• show Staking in sidebar and on dashboard in assets
  • in the sidebar we should not separate individual staking accounts, but show only one total sum of staked amount across all accounts

Design

• https://www.figma.com/design/0Kz3w6WDlvQm62RjOm87na/Staking?node-id=6441-8189&node-type=frame&t=O6DhHaULvf1ex7cE-0

Acceptance criteria

• The staking tab in Solana displays a list of all staking accounts attached to the Sol account and their staked balance
  • Even staking accounts created via a 3rd party wallet should be displayed
