[CONTRACT] feat: Restrict set_daily_word to One Call Per Day & Update end_of_day_timestamp

[manlikeHB]

Description
Currently, set_daily_word can be called multiple times per day, which could lead to inconsistencies. To prevent unintended overwrites, we need to ensure that the function can only be called once per day. Additionally, when setting a new word, the end_of_day_timestamp should automatically update to reflect the next day’s reset time.

Acceptance Criteria

• set_daily_word cannot be called more than once per day.
• end_of_day_timestamp updates automatically upon setting a new word.
• Write unit tests to verify correct behavior.

Hi @manlikeHB , its Anushka here.
here's how i would approach this issue if i'm given the opportunity
I'll implement this by storing a last_set_timestamp in storage and ensuring that set_daily_word can only be called if the current timestamp has passed end_of_day_timestamp. If it's still within the same day, the function will revert. Once a new word is set, end_of_day_timestamp will automatically update to reflect the next reset time either at midnight UTC or by adding 86400 seconds to the last set timestamp. I'll also write unit tests to verify that the function correctly restricts multiple calls within a day, updates the timestamp properly and handles edge cases like calls near the reset boundary.

Hey! I'd love to take this on. I'll ensure set_daily_word is restricted to once per day while automatically updating end_of_day_timestamp. I'll also cover it with unit tests for reliability. Assigning this to me!
