Describe the bug
Both of the stories below implement the "Sample per Pool" validation for scRNA cDNA Prep Submission with different error messages. Pool sizes for a study-project are found by the division number_of_samples / number_of_pools. The size of some of the pools (or all) will be equal to the quotient. The size of some of the pools will be the quotient plus one if there is a remainder.

• Y24-402 - Specify 'no. pools' rather than 'no. samples per pool' in submission Y24-402 - Specify 'no. pools' rather than 'no. samples per pool' in submission #4423
  Excerpt from acceptance criteria: "Number of samples per pool' (to be calculated - see additional context) must be between 5 and 25 (inclusive)"
  Error messages:
  There is a separate error message for each possible pool. They are numbered as pool number 1, pool number 2, pool number 3, and so on.
  Comments:
  There is no need to check the range and repeat the same error for each possible pool. There are only two possible sizes (quotient and quotient plus one), independent of how many pools there are (one to eight).
  The number of error messages can be as high as 8 while only the "pool number" is different in them.
  Screenshot: See the red rectangle below

• Y24-429 - Check feasibility of cDNA Prep submission Y24-429 - Check feasibility of cDNA Prep submission #4460
  Excerpt from acceptance criteria: "The number of pools requested must be feasible given the number of samples"
  Error messages:
  There is a separate error message only for the smallest and biggest pools. If the smallest and biggest pools are the same or the number_of_pools is one, the error is reported only for the smallest pool.
  Comments:
  Only the smallest and biggest pools sizes are checked and reported.
  Screenshot: See the blue rectangle below

The following screenshot shows an example when the number of samples is 10 and number of pools is 3.

number_of_samples/number_of_pools = 10/3
Quotient = 3
Remainder = 1
Pool sizes: 3, 3, 4
Smallest pool size: 3
Biggest pool size: 4

To Reproduce
Steps to reproduce the behaviour:
See the notes for manual testing at #4460 (comment) .
Change the number of pools in the spreadsheet to make the quotient of the division number_of_samples / number_of_pools or the quotient plus one outside of the range 5 to 25.

Expected behaviour

• Remove the duplicated validation of the same condition.
• Provide concise error messages to help user.
