Deposit on Enzyme hack

[kenkunz]

Goal

As a strategy admin, I want a "Deposit at Enzyme" alternate deposit path for a strategy that does not yet have a working deposit flow, so that I can demo the strategy.

Background

See #824. While this effort is in-progress, we need a lightweight way to still demo a deposit on the new strategy.

Acceptance criteria

1. The frontend strategy configuration format includes a new optional boolean property: depositOnEnzyme
2. When a strategy is configured with depositOnEnzyme=true, the deposit widget shown on the strategy overview page includes a "Deposit at Enzyme" button in place of the normal "Deposit" button, which links to the associated vault overview page.
