feat: add emoji reactions to reviews

[andrebolina]

Problem statement

Users currently have no way to interact with a review to express agreement, disagreement, or other sentiments. This makes it difficult to determine if a specific review represents a community consensus or if it is just an isolated, individual perspective.

Proposed solution

Add the ability to react to reviews using a pre-defined list of emojis. This interaction should be available on both the individual profile page and the main feed timeline.
