Summary: Ref T13411. This cleans up policy name rendering. We ultimately render into three contexts: - Plain text contexts, like `bin/policy show`. - Transaction contexts, where we're showing a policy change. In these cases, we link some policies (like project policies and custom policies) but the links go directly to the relevant object or a minimal explanation of the change. We don't link policies like "All Users". - Capability contexts, where we're describing a capability, like "Can Push" or cases in Applicaitons. In these cases, we link all policies to the full policy explanation flow. Test Plan: - Used `bin/policy show` to examine the policy of an object with a project policy, no longer saw HTML. - Viewed the transaction logs of Applications (ModularTransactions) and Tasks (not ModularTransactions) with policy edits, including project and custom policies. - Clicked "Custom Policy" in both logs, got consistent dialogs. - Viewed application detail pages, saw all capabities linked to explanatory capability dialogs. The value of having this dialog is that the user can get a full explanation of special rules even if the policy is something mundane like "All Users".
