Reorganize Settings screen and register up/down direction icons

[NathanNeurotic]

Motivation

• Improve the Settings page layout to be more organized and fluent by placing the page title and BDMA control at the top and grouping the POPStarter profile section below it.
• Surface missing directional icons so navigation affordances (left/right for BDMA, up/down for profile selection) are visually present.

Description

• Register up and down assets in bin/POPSLDR/images.lua so IMG.up and IMG.down resolve at runtime.
• Update UI.ProfileQuery.Play in bin/POPSLDR/ui.lua to change the top title to "Settings" and move the BDMA Mode row directly under the title while keeping the existing left/right icon rendering around the BDMA value.
• Group the POPStarter profile section below BDMA by drawing "Choose POPStarter Profile" (with IMG.up and IMG.down shown on the left/right), then rendering Profile X, the profile description, and the POPSTARTER.ELF path together below it.
• Preserve all existing input/event handling and behavior (UP/DOWN still change profile, LEFT/RIGHT still change BDMA); only presentation/layout code was adjusted.

Testing

• Verified the file diffs and contents to confirm bin/POPSLDR/images.lua contains {"up","up.png"} and {"down","down.png"} and bin/POPSLDR/ui.lua contains the updated UI.ProfileQuery.Play layout, with automated text search confirming the expected lines were inserted.
• Confirmed diffs show only the two intended files were modified and the overall patch size is 2 files changed, 18 insertions(+), 5 deletions(-).
• Executed automated file inspections that validated IMG.up/IMG.down references exist and the BDMA/profile drawing logic was repositioned as required, and those checks passed.

Code Review

This pull request reorganizes the Settings screen for better layout and adds up/down directional icons. The changes in images.lua to register the new icons are correct. In ui.lua, the layout logic is updated as described. I've identified a potential crash if no POPStarter profiles are configured and suggested a fix. I also have a couple of suggestions to improve the maintainability of the layout code by replacing magic numbers with named constants and addressing a potential visual imbalance due to asymmetric icon positioning.

[gemini-code-assist]

If PLDR.PROFILES is empty, profcnt will be 0. UI.ProfileQuery.curopt could still be 1, which would cause a crash on these lines when trying to access fields on a nil value. The entire block for drawing the profile selection (lines 1255-1267) should be wrapped in an if profcnt > 0 then ... end block to prevent this.

[gemini-code-assist]

This function uses several magic numbers for vertical positioning of UI elements (e.g., 92, 30, 78, 128). This also applies to the 30 used for mode_y on line 1243. To improve readability and maintainability, consider defining these as named constants within the UI.LAYOUT table. This would make the layout logic clearer and easier to adjust in the future.

[gemini-code-assist]

The horizontal offsets for the up and down icons (-150 and +128 from screen center) are asymmetric. Since the text 'Choose POPStarter Profile' is constant and centered, one would expect symmetric offsets for the icons on either side for visual balance. If this asymmetry is not intentional (e.g., to account for different icon widths), consider using symmetric values like -150 and +150.
