Spacing of service menu list entries is inconsistent

Certain service menus in 0.49.0 have a number of inconsistencies with Morrowind, the most notable of them being the number of spaces between the service item, its cost and the dash between them. Spell buying window (addressed by !4571 (merged)) and travel window (!4568 (merged)) use 3 spaces while the repair window (!4588 (merged)) uses 1 space. Morrowind uses 2 spaces after the item (probably to accentuate it) and 1 space before the cost.

On a technically unrelated but notable point which doesn't quite deserve its own issue, the Travel caption of the travel window is not properly centered, which is addressed by !4569 (merged). The relevant MRs also make an attempt to make the windows resemble the original windows more in other respects.
