[4.x] Cast id to string to avoid snowflake ids being treated as floats

[RhysLees]

Using snowflakes instead of standard ids causes ids to be treated as floats changing the id.

for example task.id is 420533451316027392 when using

@js(['recordKey' => $record['id']]))"

the snowflake is being treated by js as a float and losing precision so casting to a string resolves this.

@js(['recordKey' => (string) $record['id']]))"

Closes #88

Thanks for the fix @RhysLees! Your root cause analysis was spot on.

Closing this in favor of #91 (3.x) and #92 (4.x) which apply the fix at the data layer in formatBoardRecord() instead of the Blade template. This way the ID is always a string for any downstream usage, preventing the same issue from recurring if new templates or JS paths are added.
