Add CreatePost lib component

[Gizmotronn]

Allow users to create posts on our client.

• User creates post (proposal Proposal Board → Migration from Vite) with the NFT ID for their anomaly and some extra metadata for their discoveries and proposal, and then users can vote

This will allow us to determine how we attach additional metadata to our publications.

Here's a demo metadata tag:

const postMetadata = {
            version: '2.0.0',
            mainContentFocus: PublicationMainFocus.Image, // This can be changed -> what post type is being created?
            matadata_id: uuidv4(),
            description: description,
            locale: 'en-us',
            content: content,
            external_url: null,
            image: imageIpfsUrl,
            imageMimeType: null,
            name: title,
            attributes: [],
            classificationMetadata: classificationMetadata,
            tags: ['0xed6e837Fda815FBf78E8E7266482c5Be80bC4bF9'],
            appId: 'ssk_example',
};

Potentially, one of the tags could point to the contract → nft id that is being referenced (note that classificationMetadata is a custom prop.

As seen here, the post now shows up with the image field, while on my Lenster profile, the image isn't shown:

We now need to create a query to set the maximum width of a post, and also create a method to hide comments (those should show up underneath a post).

Based on this behaviour, I'm now expecting that we can add additional metadata tags (as seen in lib/useCreatePostProposalEdit on signal-k/client) and have them only be displayed on our client.

New styling issue needs to be referenced in Signal-K/client#9 & Signal-K/client#8 however
