fix: decode flow cap activity details

[Seranged]

Summary

• Decode serialized Euler Earn Public Allocator flow-cap configs into readable per-strategy limit details.
• Resolve strategy vaults and format maximum inflow and outflow in the Earn vault underlying asset units.

Changes

• Parse and validate FlowCapsConfig payloads with a raw fallback for malformed or future shapes.
• Show a compact strategy count while collapsed and linked per-strategy limits when expanded.
• Display set_flow_caps events as Public allocator limits updated.
• Hydrate strategy metadata and cover decoding, formatting, resolution, labeling, and fallback behavior with tests.

Preview

• Open the Monad Earn vault on the PR 801 Railway preview

Test plan

• npm run build
• npm run lint
• npm run typecheck
• npm run test:run
• Verified collapsed and expanded Public Allocator limit activity on the PR 801 Railway preview.

Summary by CodeRabbit

• New Features

  • Activity details now show additional metadata alongside relevant addresses.
  • Flow-cap changes display strategy details, including maximum incoming and outgoing amounts.
  • Vault and explorer addresses in flow-cap activity entries are linked for easier navigation.
  • Flow-cap activities use clearer “Public allocator limits updated” labeling.

• Bug Fixes

  • Invalid or incomplete flow-cap configurations retain available raw details.
  • Address rows can wrap content for improved readability.

📝 Walkthrough

Walkthrough

Flow-cap configurations are parsed and formatted as strategy entries. Strategy addresses are included in vault resolution. Activity rows render optional metadata beside address links.

Changes

Flow-cap activity display

Layer / File(s)	Summary
Parse and format flow-cap changes utils/activity-display.ts, tests/utils/activity-display.test.ts	Validates serialized set_flow_caps configurations and creates formatted strategy entries with links and maximum inbound/outbound caps. Tests cover valid and malformed configurations.
Resolve flow-cap strategy addresses utils/activity-display.ts, tests/utils/activity-display.test.ts	Includes strategy identifiers in vault address resolution. Tests cover labels, links, extracted addresses, and fallback output.
Render address metadata components/entities/activity/ActivityEventRow.vue, utils/activity-display.ts	Preserves optional address metadata and displays it beside wrapping address links.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Review summary

No high-severity issues found. This is a display-only change that decodes Earn set_flow_caps configs into strategy rows with max-in/max-out amounts; parsing fails closed to the raw config string, amounts stay in bigint via formatUnits, and units correctly come from the Earn vault underlying asset (matching PublicAllocator semantics).

Reviewed: utils/activity-display.ts, components/entities/activity/ActivityEventRow.vue, tests/utils/activity-display.test.ts · Traced beyond the diff: resolveChangeAddresses / vault metadata lookup, formatActivityTokenAmount, getActivityResolvableVaultAddresses → ActivityEventRow hydration, Earn PublicAllocator FlowCaps / MAX_SETTABLE_FLOW_CAP · Protocol skills consulted: euler-earn

Not flagged

• No Unlimited mapping for flow caps: unlike Earn allocation caps (UINT136_MAX), PublicAllocator has no unlimited sentinel (MAX_SETTABLE_FLOW_CAP = type(uint128).max / 2); treating that as Unlimited would be inventing protocol meaning.
• String-only maxIn/maxOut validation is intentional given nested JSON and uint128 range; author verified against a live Monad Earn vault.
• XSS surface is text interpolation only ({{ detail.addressDetails[...] }}); no v-html.
