- Encoder: add encodeWhalesWithdraw (op 0xDA803EFD) and encodeTfWithdraw,
  export fee constants (STAKE_GAS_RESERVE_TON, UNSTAKE_*_GAS_TON)
- Hook: branch useEncodeStakingUnstake by pool.implementation
  (Whales/Tf/LiquidTf), add isSendAll for Whales amount=0 optimization
- UnstakeForm: TF auto-fills full balance + disables input,
  pool-aware fee check, Whales isSendAll when amount matches balance
- Pool detail: Claim button for non-liquid pools when readyWithdraw > 0,
  error state fallback, date locale via useDateFormat hook
- usePoolInfo: gate on STAKING feature flag, fix cache key (drop amounts)
- StakingAmountInput: import STAKE_GAS_RESERVE_TON from encoder
- usePortfolioBalances: console.warn for dropped staking positions

- Extract usePoolStakedBalance hook to centralize liquid/non-liquid balance fetching
- UnstakeForm always operates in TON (matching iOS), converts TON→tsTON on confirm
- Encoder encodeUnstake supports isSendAll for liquid pools (fresh on-chain balance)
- Add convertTonToPoolTokenNano with ROUND_DOWN to prevent over-balance burns
- Fix StakingEarningsInfo: works for non-liquid pools, correct units for liquid
- Simplify PoolDetailPage by replacing ~60 lines of manual resolution with hook
- Align getStakingPoolTonAmount priority: liquid balance checked before position

…akingForm

Extract shared AmountField visual primitive, UnstakeAmountInput and
UnstakeButton — mirroring StakingAmountInput/StakingButton pattern.
Eliminates 130 lines of duplicated styled-components.

…nav handlers

Return null instead of '' when timer expires. Separate liquid/non-liquid
cycle info in UnstakeForm into independent blocks.

Move the visual sign prefixes ("+" and "—") out of staking_action_stake
and staking_action_unstake locale strings into a separate <ActionSign>
element in the component, matching the pattern used by home action
buttons (BuyIcon, SellIcon). Rebuild locales with latest Tolgee data.
