fix: re-enable Confirm Delete after a delete, so a second one needs no reopen (closes #335)

The password route disabled its Confirm Delete button before the decrypt
and never re-enabled it on success, so a second delete in the same popup
session found a dead button until the popup was closed and reopened. The
lost-password route re-enabled its own button in its leave hook, so the
two screens on the one screen behaved differently.

Both routes now reset the button through the shared finishDelete(), the
one path they both take, and the lost-password leave hook no longer
handles it separately. Tests drive a password-route delete and a second
delete in the same session; they fail against the prior head, where the
button stays disabled after the first delete.

-
-- A formatted quantity, e.g. `17.1900 USDT`: the token's scale is known and the
-  figure is at or above the floor, or below it and extended to its first
-  significant digit. This is `truncateAmountNeverZero()`
-  (`src/shared/amountDisplay.js`).
-- `Unlimited`: an unbounded allowance or permit, which needs no scale to
-  describe — a `uint256`-max ERC-20 `approve` (`src/popup/views/approval.js`) or
-  a Permit2 amount at the `uint160` max on a swap's `Amount`
-  (`src/shared/uniswap.js`).
-- `All available (V4 open delta)`: a V4 exact-in swap whose `amountIn` is zero.
-  V4 reads that zero as "use the whole open delta", not as a literal zero, so
-  the calldata states no quantity at all. Swap `Amount` line only
-  (`src/shared/uniswap.js`).
-- `None (no minimum guaranteed)`: a zero minimum — the swap guarantees nothing
-  back. It is a literal zero slippage floor on a V2/V3/V4 swap, and it also
-  reaches a `BALANCE_CHECK_ERC20` step: a zero `minBalance`, which once rendered
-  `0.0000` beside the token symbol, now reads this. Swap `Min. received` line
-  (`src/shared/uniswap.js`).
-- `<amount> base units (decimals unknown)`: the token's scale could not be
-  resolved, so the base-unit integer is shown with that caveat rather than
-  formatted (see Unknown token scale above). Reaches both the ERC-20 amount line
-  and the swap's `Amount` and `Min. received` (`unknownDecimalsAmount()` in
-  `src/shared/approvalAmount.js`).
-- `Unknown (not named in the calldata)`: not an amount but the currency itself —
-  the `Token In` or `Token Out` line when nothing in the calldata established
-  which token, shown beside the amount and, like the strings above, a sentence
-  rather than a value (`src/shared/uniswap.js`).
