Feat/root claim in wallet change default bittensor validator

Bittensor staking: remark constant, root claim guidance, rewards removal + dep bumps

Summary

Changes to the Bittensor (subtensor) staking flow in the portal, plus a dependency audit fix:

1. Centralize the stake remark — introduce a TALISMAN_STAKE_REMARK constant ('paprika005') and use it for every remarkWithEvent call, replacing the hardcoded 'talisman-bittensor' string.
2. Guide root stake claims to the Talisman wallet — root subnet (netuid 0) rewards can't be claimed from the portal, so the positions table now renders a Claim button that points users to the Talisman wallet.
3. Remove reward calculations for bittensor positions — the "Total rewards (all time)" column no longer computes or displays anything for bittensor rows, dropping an expensive all-pages delegation-event fetch.
4. Patch dependency audit advisories — bump postcss and eslint.

Changes

Stake remark constant

• Add TALISMAN_STAKE_REMARK = 'paprika005' in constants.ts.
• Replace all remarkWithEvent('talisman-bittensor') calls with remarkWithEvent(TALISMAN_STAKE_REMARK) in forms.ts and useMoveStake.ts.

Single source of truth for the on-chain remark tag, so future changes touch one line.

Root stake claim button

• Add TALISMAN_WALLET_DOWNLOAD_URL = 'https://talisman.xyz/download' in constants.ts.
• In StakeItemRow, render a claimButton only for root stakes (netuid === ROOT_NETUID):
  • Claim button with an Info leading icon.
  • Tooltip on hover: "Root subnet rewards are claimed in the Talisman wallet. Click to download."
  • Click opens the Talisman wallet download page in a new tab (noopener,noreferrer).
• Non-root positions are unchanged (empty claim cell).

Remove reward calculations for bittensor positions

Bittensor reward totals were derived by paginating every delegation event for the nominator, then summed and shown in the "Total rewards (all time)" column. Removed entirely; the column now renders nothing for bittensor rows.

• Delete useGetRewardsByNominator and its only-consumers useGetInfiniteDelegationEvents and useGetDTaoStakedBalances.
• Drop rewards / rewardsFormatted fields and isRewardsLoading from useStake / StakeItem.
• Stop passing rewards, fiatRewards, isRewardsLoading from StakeItemRow; the shared StakePosition recipe auto-hides the column when both are absent (shouldRenderTotalRewards = props.rewards || props.fiatRewards).

Scoped to subtensor only — other providers (nom pools, dApp staking, validators, Lido, seek) keep their reward totals, and the shared recipe is untouched.

Dependency audit fixes

• postcss ^8.5.19 → ^8.5.26 — fixes GHSA-fxqj-rqcc-2cmp (arbitrary .map read via attacker-controlled sourceMappingURL when from is unset).
• eslint ^9.2.0 → ^9.39.5 — move to the latest supported 9.x.

Note: the eslint deprecation advisory only fully clears on eslint 10, which is currently blocked upstream — eslint-plugin-react (latest 7.37.5) declares peer support only up to ^9.7. Held at latest 9.x until it ships v10 support.

Testing

• tsc --noEmit passes.
• Root stake position renders the Claim button; hover shows the tooltip; click opens the wallet download page.
• Non-root positions render no claim button.
• Rewards column renders nothing for bittensor rows; other providers' reward totals unchanged.
