refactor: deploy only equity, bond and deposit tokens

[MiguelLZPF]

Description

BBND-1882 [SERVICING] — deploy-layer cleanup.

Clean the deploy scripts and Factory so the system deploys only Equity, Bond (variable-rate) and DepositToken. Removes the Loan, LoansPortfolio, BondFixedRate and BondKpiLinkedRate deploy configurations, the Factory `SecurityType` entries for them, their deploy fixtures and per-type deploy tests, and renumbers the deployment-workflow steps and checkpoint indices. The underlying Solidity facets for those types are intentionally retained (deploy-layer only) and remain exercised by the shared AssetMock mega-asset; the deprecated SDK and the web app are untouched.

Note for reviewers: The Factory `SecurityType` enum was trimmed, which shifts `DepositToken`'s ordinal from 5 to 2. All Solidity references use the enum by name, so this is ABI-enum-visible but internally safe.
