### Context

Handling large anchor data (validation and rendering) is problematic on GovTool, ranging from insufficient display to browser crashing.

Here are some test cases:

Test no | Name | GovTool Output | Comments | Action Id
-- | -- | -- | -- | --
1 | Simple valid file | All OK | All OK | 059fdaf7919525863f2e7625aaf959301e4e56176617ce7283435ee137c56e26#0
2 | Out of context file | Data Formatted Incorrectly | Gov tool doesn't support invalid json that is outside of cips context | 8b8fe0ff42c9718caa7a05441eed4e1d75274350a319575031302f1cc71e0107#0
3 | Title greater than 80 | Data Formatted Incorrectly | Expected but proper error could be shown to inform what was wrong | d3ad66dad758696180850f9f090138c9c35de3717fe337875b5f7de37349876e#0
4 | Abstract greater than 2500 | Data Formatted Incorrectly | Expected but proper error could be shown to inform what was wrong | 4de5fbb44b6336298fd6ef7daf1a1ef75c47c532b0cd13a1e48c3aab86e1d701#0
5 | 100KB content rationale | Read/Parse OK but -> | Rationale text is truncated | 2a76c7f9b35de7571528872fca4502656f006143863c5321c3801b28f8100d3b#0

7 | 10MB content rationale | Except rationale other fields are parsed | Clicking on view details and vote feel laggy. No text shown on rationale. | 987ed32dd01b363ad3dad7d7b09556c70ddc143f1ad7c4b4afc95ade3628518b#0
8 | 100MB content rationale | Browser crahsed | Likely high memory usage | 3ded0413648c1abb1e34cd03e1b545555069b78a02d4c33c7414b31da940717a#0

### Steps to reproduce

1. On sanchonet deployment, compose the governance_actions URL using the Action ID.
{BASE_URL}/connected/governance_actions/{ACTION ID}
For eg. case 2: [8b8fe0ff42c9718caa7a05441eed4e1d75274350a319575031302f1cc71e0107#0](https://dev-sanchonet.govtool.byron.network/connected/governance_actions/8b8fe0ff42c9718caa7a05441eed4e1d75274350a319575031302f1cc71e0107#0)
2. Observe the rendering of the governance action on GovTool.
3. With the increasing content size, the loading of the page and responsiveness seems to diminish and finally crashes (browser).

### Actual behavior

- Missing proper error messages
- Text truncation can be better
- Browser crashes for large content

### Expected behavior

- Lazy loading or warning on large content processing on the frontend
- Browser does not crash
