No need to panic it is just matter of time and individual application.

1, only stamped pages should be fine, I did all pages with single of pdf file each passport. Three pdf file of three passports (one was totally blank passport as yours). No need for covering letter.
2, Yes, no need to sign back of the photo

Biometric deadline will not affect your application due covid. This has been to told by UKVI.
If you have doubt send twit to them, will respond immediately

For passport photos check Sainsbury's/asda some other shops they might have self photobooths about printing and scanning try to borrow from friends or buy one as they are not expensive, your application may not be refused for this but may be delayed.

2] IHS is usually given by the applicant.

The OP is asking about the sponsor ISC not IHS.

My apologies, I misread it.
Please ignore it

1] For extension, you no need to prove maintenance.
2] IHS is usually given by the applicant.

Book an appointment, bookings are open.

I have on this Wednesday for my family

You will get partial unused IHS eventually.

You cannot change the duration of the visa, ask your employer to change end date in Cos.

this not an immigration question, contact a CA

you are not submitting only digital.

you are free to travel

my understanding is that, your company supports first 3 months or 1month of your job.
if your applying after this period, you have to show mantainence.

yes, pp number

any communication within 24hrs means you wont get refund.
if you did not get any communication few days then request for refund.

That is one of the main requirements for ICT visa.

Online submission date is application date.
my understanding is that, they get cos anytime, there is no time restrictions.

I suggest applying just before your dependents visa expiry.
very minimal documentation for Extention, you should submit the form online a day before 15th Jan.

Why did you send originals by post?

Once you uploaded all documents and did biometrics that's all, just wait, it might take up to 6 months for your approval.
